What does Particle 'Concentration' Mean in Particle Sizing?

'Concentration' displayed in particle size distribution measurement usually indicates the intensity of the received light signals, which is related to the number of particles, usually called 'optical concentration' instead of 'percentage concentration'. For laser particle sizing, the more particles in the suspension, the higher the optical concentration. However, when there are too many particles in the suspension, the optical density will be reduced if the light is overscreened.
For the sedimentation method, the more particles in the suspension, the lower the optical concentration.

          

Outstanding Quality of Bettersize Products

Many people have no faith in the quality of the particle size analyzers made in China. However, Bettersize has been dedicated to improving product quality in the last 24 years. Great effort in innovation and strict quality management has made the quality of Bettersize particle size analyzer internationally recognized. 

Particle size analyzer is always equipped with a ultrasonic disperser. Since it operates under high pressure and user may misoperate, its failure rate is relatively high. To solve this problem, voltage and current sampling and frequency adaptive systems are employed to ensure stable voltage output and the best dispersion effect. At the same time, Bettersize ultrasonic disperser has a unique anti-idling system, which will make sure the apparatus undamaged when there is no water in the circulation tank. The average trouble-free operating time of Bettersize ultrasonic dispersers is more than 3,000 days.

Every distinguished laser particle size analyzer requires good alignment functioning. Poor alignment can lead to inaccurate test results. Since the alignment hole is very small and nearly invisible to naked eyes, once the misalignment occurs, it is difficult for users to fix it by themselves. Each Bettersize laser particle size analyzer is equipped with an automatic alignment system, which will run with a mouse click, ensuring that the laser particle size analyzer always works in its best state.

In recent years, instruments innovated and made by Bettersize have been exported to 50 countries around the world such as the United States, Germany, South Korea, Brazil, Argentina, Japan, India and Russia. The performance and quality of the instruments have been widely recognized by Bettersize’s global partners and users. 

Details can make incredible differences. After twenty-four years of development, Bettersize has established a set of concepts and methods for creating high-quality products, ensuring that each set of instrument meets the standards. We believe Bettersize will be an internationally advanced particle size analyzer manufacturer in the future.

How to Choose the Analysis Modes?

In the latest version of the software of the Bettersize laser particle size analyzer, three modes of analysis are set: "General",  "Multi-peak", and "R-R distribution" analysis modes. The "General" mode is a versatile mode that is suitable for approximately 80% of samples, including monodisperse standard samples and multimodal samples.Therefore, the "General" mode is the preferred mode of analysis.

Compared with the general mode, the "Multi-peak" mode is a higher resolution mode. It is usually selected when the results from the "General"mode are not good or when it is determined to be a multi-peak sample. The selected ratio for the multi-peak mode is about 15%. ‘R-R distribution’ is a fixed mode that is used only for special occasions and uses less than 5%.

How to Verify the Resolution of A Laser Particle Size Analyzer?

Resolution is defined as the minimum difference between two samples that can be effectively distinguished by a laser particle size analyzer. As important as repeatability and accuracy, resolution is one of the main indexes and used to evaluate the performance of a laser particle size analyzer.

Since there is no standard sample to evaluate the resolution of laser particle size analyzer, it is difficult to quantitatively assess the resolution. Users can qualitatively evaluate the resolution by a simple method: 1:1 mix two standard samples with nominal values >5. If two peaks were obtained, the resolution would be high and the instrument qualified. Furthermore, if the baseline is also separated (the maximum end of sample A is separated from the minimum end of sample B), the resolution is very high and the instrument is excellent.

How to Control Shading Ratio?

There are two methods to control shading ratio. The first method is multiple sampling: adding small amounts of samples for multiple times and observe the changing of shading ratio. When reach the pre-set value, then stop adding samples and start test procedure. The second method is sampling with the fixed amount. For powder samples of the same grade, the amount of the sample to achieve the optimal shading ratio is firstly determined by experiments. Subsequently, the same amount of samples measured by balance can be used for each measurement. It can achieve the required optimal range of shading ratio at one time.

Bettersize Group Visit Southeast Asia for Client Reviews

In the stifling July this year, sales manager of BETTERSIZE INSTRUMENTS, Lin Sun visited our customers in Southeast Asia. It was the forth time he had visited this area in summer. He said, “Although going out in such hot weather is a tough thing, it is more important to get connected to our customers. That’s why I visit there annually.”

To serve our customers better, the sales service manager of BETTERSIZE, Dongrui Hou also joint this visit. The tour this year starts from Thailand. We co-host a seminar with our partner, BRENNTAG GROP in Thailand. The seminar was targeted on customers in pesticide industry. We simulated the whole production procedures from sample preparation, grinding to the final test of finished products.

The seminar was divided into two parts. First we made a technical communication and introduction by presentation.

Then we let the customers operate the instruments by themselves in the afternoon under the guidance of our sales service manager.

We met more than 40 customers from 15 different companies during the seminar, thanks to our partner BRENNTAG GROUP, who helped us in gathering and communicating with the customers.

We had a great time with BRENNTAG GROUP.

After the seminar, we visited our regular customer SPKG. The manager of SPK company, Mr. Sanya, recommended our product to his friends after using our instrument for one year. Our sales manager carried out thorough maintenance of customer's instrument.

Then we left Thailand for Kuala Lumpur, Malaysia to visit local industry-leading coating producers and a pesticide producer. The meeting was quite satisfactory.

We also visited a customer, manager of a well-known company in Penang, Mr. Shaw to give a detailed feedback to the questions they have and help them to operate more smoothly.

Heading to the north, we arrived in Ho Chi Minh City, Vietnam to visit the manager of CK PORCELAIN, Mr. Wu. He has used our instrument for seven years and he always recommend our instrument to other companies. Our sales service manager did a complete maintenance for customer’s instrument.

The Relationship Between Mesh and Micron (μm)

Mesh is the unit to measure the pore size of a sieve, defined as the number of pores per inch in a sieve. The larger the mesh, the smaller the pores. Because the standard in different countries varies, the conversion of mesh to micron is also different.

The table below shows the conversion of mesh and micron (for reference only).

Bulk Density, Tap Density and Compression Ratio

Bulk density: fill the powder sample into a measuring cup, flatten the top, the ratio of the powder mass to the volume of the cup is defined as bulk density. It indicates the mass of the powder that can be added into the vessel per volume under the normal conditions.

Tap density measurement: fill the powder sample into a measuring cup; vibrate the cup at certain amplitude and frequency to remove air from the powders. After reaching the required vibration time, flatten the sample. The ratio of the powder mass to the volume of the cup is defined as tap density. Tap density indicates the mass of powders filled into the vessel per volume after excluding air from the powders. The data of bulk density and tap density are often used for the design of vessels, bags, and tanks for powder storage.

Compression ratio: it is the ratio of the difference between tap density and bulk density to tap density. It shows the degree of volume reduction from bulk to tap state.

Original Developed Technology DLOS (Dual Lens Optical System)

Asia Pacific Coatings Show 2019

The well-known International Asia Pacific Coatings Show was held on 4th - 6th September, 2019 in Bangkok International Trade and Exhibition Center. There are over 170 exhibitors present at the exhibition. Bettersize team showed their latest technologies and instruments for particle size as well as particle shape analysis professionally and actively.

There are a large variety of coatings with different usage. Coatings are mainly divided into water-based coatings, solvent-based coatings and powder coatings. And the main components of coatings are pigments, fillers and resins. The particle size distribution and flowability of powder coatings are closely associated with their transfer efficiency as well as recovery efficiency, while the particle size distribution of fillers and pigments will influence tinting strength , hiding powder, gloss and smoothness of the coatings. Besides, particle size distribution also impacts on the dispersibility, oil absorption and storage stability of pigments and fillers. The molecular weight of resins will also greatly affects their viscosity, film build-up performance and the volume of volatile organic compounds (VOC). By controlling particle size distribution, the same or a better performance of the film can be realized by consuming less raw materials. In addition, by controlling the molecular weight of the resins, viscosity and solvent content of the coatings can be properly restraint, reaching the goal of environmentally friendly production.

As the environmental protection laws get improved progressively, the costs for the production and development of coatings are escalating. Pigments and fillers with appropriate particle size distribution and good dispersibility can save  production capacity, spare the use of resins and raise productivity.

The different demands of our users can be satisfied: particle size and particle shape analysis of ingredients as well as final products; dispersibility check and molecular weight measurement of powder materials; functional indexes of powder materials. Bettersize laser particle size analyzer can measure the particle size distribution of pigments, fillers, resins and compound products which can fulfil the quality control of final products, while through imaging particle size and particle shape analyzer, the particle shape and dispersing state can be observed. Resin, which greatly influences the performance of the coatings, is an indispensable component. Nanoptic 90 nanoparticle size analyzer can not only measure the particle size distribution of resins in water or solvents but also their molecular weights. As for Bettersize powder characteristic tester, it can provide functional indexes, such as bulk density, tapped density and flowability of various powder materials including pigments, fillers and chemical additives, benefiting powder transfer, package and transportation process. Bettersize instruments can be used in nearly all aspects of coating production from raw material inspection to the quality control, package and transportation of the final products.

At the exhibition, many visitors showed great interest in the technologies of Bettersize and stopped by our booth. From time to time, our booth was crowded with visitors. Some of the clients took their products to our booth, and we demonstrated the measurement procedures. Also we explained the theories of our instruments and the indications of the analysis report carefully. Surprisingly, we met many “old friends” at this show, who were our regular customers, including prominent filler companies, metallic pigment producers and water-based slurry producers. Bettersize has been working in coatings industry for decades, and has attracted a number of customers at this exhibition with its professional attitude and trustworthy technologies.

The Asia Pacific Coatings Show was concluded on 6th September. We found it quite fulfilling, with our professional attitudes and technologies demonstrated. More importantly, we penetrated further into coatings industry and knew more about the market demands.

After the exhibition ended, our sales manager, Lin Sun visited Sigma corporation and Sharp company in Thailand to communicate and get feedback. Mutual trust and win-win cooperation relationship were set up.

As far as this exhibition is concerned, Bettersize team has had a quite rewarding experience. We look forward to seeing you soon.

Bettersizer ST Operation Procedures of BT-800N

South Europe

Angle of Repose, Angle of Fall, Angle of Difference, Angle of Spatula

Angle of Repose: Under the static balance, the angle between the slope of a powder pile and the horizontal plane is Angle of Repose. It is measured when the powders fall to a surface via gravity and form a cone. It indicates the flowability of the powders. The smaller the Angle of Repose is, the better the flowability of the powders.

Angle of Fall: After measuring the Angle of Repose, apply an external force to the powder pile to collapse it. The angle between the slope of the collapsed pile and the horizontal plane is defined as Angle of Fall.

Angle of Difference: It means the difference between the Angle of Repose and the Angle of Fall. The larger the Angle of Difference is, the better flowability of the powders.

Angle of Spatula: immerse a plane in the powder pile; pull up the plane vertically, one angle is formed between the slope of the powders on the plane and the plane. Apply an external force to obtain another angle. The average of these two angles is Angle of Spatula. The smaller the Angle of Spatula is, the better the flowability of the powders. The Angle of Spatula is usually larger than the Angle of Repose.

The Advantages of Bettersize Laser & Imaging Particle Analyzer

Bettersizer S3 Plus laser & imaging particle analysis system combined laser scattering and microscopic imaging for particle sizing and morphology analysis. In terms of particle sizing , the combination of two test methods could improve the accuracy of measurement, especially for ultra-fine and large particles.

Background of Laser Particle Size Analyzer

Background is optical signal formed on the detectors after the laser passed the sample cell with clean medium. The main cause for background signals is laser refraction/reflection when go through air, medium and sample cell. Besides, pollution of lens, medium, and sample cell may contribute to the background. The purpose of measuring background is to deduct these fixed and not-sample-related signals from sample light scattering during measurements. It guarantees the accuracy and reliability of the measuring results.

What is Particle Sizing Reference Material?

The calibration of a particle size analyzer can be performed using certificated reference material (CRM) or general reference material (RM). CRM was verified by the qualified or regulatory departments and the data was released with scheduled dates. At present, the absolute measurement method in China is the microscopic method. Its scale is traceable to the length standard. Usually, the scale bar is 10μm and the smallest scale has now reached 416nm.
In addition to accurate size value, a RM should possess the following properties:
(1) The material is stable and no size change within a certain period (e.g., 1 year);
(2) Monodisperse particles, that is, the coefficient of variation for particle size distribution is as small as possible. Usually, the coefficient of variation is ≤3% for grade 1 RM and in the range of 3% ~ 8% for grade II RM;
(3) Good spherical shape, usually requiring roundness of 95% to 98%.

Effect of Sample Concentration in Particle Sizing

In general, particle sizing is realized through the system recognition and reception of optical signals. The intensity of the light signal is determined by the number of particles in the suspension.

Taking laser method as an example, the higher the concentration of particles in suspension, the stronger the scattered light signal is; but the subsequent phenomenon of complex scattering is intensified simultaneously, which affects the measurement results. On the contrary, the lower the concentration of particles in suspension, although the phenomenon of complex scattering is alleviated, the decrease of signal-to-noise ratio and the lack of representativeness also affect the measurement results.

The situation is similar for other particle sizing methods. Therefore, suitable particle concentrations are very important for particle sizing.

Effect of Sample Refractive Index on Laser Particle Sizing

Ultra-fine and nano-sized powder materials are the research and production trend of modern powder materials. In order to meet the requirement of measuring these particles, the measurement range of laser particle size analyzer is developed in the direction of ultra fine and nanometer. Therefore, the measurement limit of modern high performance laser particle size analyzer has reached 20nm or even 10nm.

The refractive index of the samples (including absorptivity) is an important parameter for precise analytic solutions of Mie scattering theory. The use of incorrect refractive index would lead to incorrect measuring results. As more and more novel materials, synthetic materials and composite materials being developed, it is difficult to measure refractive index of these materials.

To solve this problem, Bettersize has developed refractive index measurement technology and applied on Bettersizer S3 series. Before the particle size measurement, the refractive index and absorptivity are firstly measured, which guarantees the accuracy of particle sizing results for new materials.

Bettersize Outward Bound

Function of Automatic Alignment System in Laser Particle Size Analyzer

The distance between the small angle detectors and the detector center is very small (about 100μm). The main beam may deviate from the detector center to the small angle detectors, due to factors such as mechanical vibration, thermal expansion, cold shrinkage, and uneven surface. The small angle detectors failed due to saturation and could not detect the scattered light signal produced by the large particles, resulting in the wrong result.

The function of the automatic alignment system is to ensure the focal point of the detector coincides with that of the Fourier lens at any time, so that the detector can effectively receive scattered light from all angles. When the optical system deviates or distorts, alignment system will run automatically. It ensure the accuracy and reliability of the measurement results, and ensure the resolution and measurement accuracy of the laser particle size analyzer.

How to Choose and Measure Refractive Index?

The refractive indices of different samples and media are different, and the Mie scattering theory is related to the refractive index, so in order to make the test results accurate, the refractive index of the measurement should be as close as possible to the actual refractive index of the sample.

The Bettersize laser particle size analyzer software system has collected and stored the refractive index of nearly 300 substances, and the same substance can be selected according to the sample

to be tested. If the sample you are testing is very specific and there is no refractive index for this sample, the refractive index can be tested with a Bettersizer S3 laser particle size analyzer and added to the refractive index database.

How to Choose a Laser Particle Size Analyzer?

An Interview with Bettersize R&D Director at IPB 2019

Lately, Bettersize Instruments attended IPB 2019 held in Shanghai.

In the past two years, the powder industry has changed a lot. The emerging high-end powder industry faces many difficulties in particular. For example, the "4+7" policy in biopharmaceutical industry and the subsidy cuts in lithium battery industry have challenged development of powder industry. While the requirements for quality and R&D of powder products in these industries are becoming higher and higher. Li Xuebing, technical director of Bettersize said that such changes have also impacted powder testing industry, which means higher requirements for the products and services of Bettersize.

For instance, users doing protein drug development now need to test the stability of powder surface charge (zeta potential) in addition to the particle size measurement. Zeta potential measurement has been monopolized by overseas particle size analysis giants. After years of research and development, Bettersize successfully launched the domestic nanoparticle Zeta potential analyzer BT-Zeta100, which can not only measure the zeta potential of a protein, but also can measure its molecular weight. In pharmaceutical industry, the costs of original drugs or drug testing are very high. For these precious samples, Dandong Bettersize has developed a micro volume sampler, which can test API samples less than 100 milligrams. What's more, legal compliance, requirements of pharmacopoeia and its explanation, as well as method development and validation are the new growing demands for measuring instrument manufacturers. Li Xuebing said that with a long history of technical developments and application research, Dandong Bettersize now can provide complete content services and method developments such as target validation, method development, cross-validation, data security protection, and audit trail as required, which can better meet the needs of users in the biopharmaceutical industry.

In the interview, Li Xuebing also introduced the development of Dandong Bettersize this year. Despite the challenges mentioned above, Dandong Bettersize is expected to maintain more than 10% growth rate in sales. The company has also made great progress this year, in the expansion of overseas markets, such as generic drug market in India, ceramics, coatings, cement in European and American as well as South America's mineral market. He emphasized that one of the goals of Dandong Bettersize is to be the "Chinese brand of internationally outstanding quality". Bettersize will contribute more input into its software and hardware improvement as well as application method development to achieve international recognition.

Finally, Li Xuebing shared his feelings and experience participating in IPB. He stressed that the huge influence of IPB is not merely because of the large number of the visitors. More importantly, IPB brings together the upstream, midstream and downstream industries to communicate and share information. Nowadays, the powder industry is confronted with various challenges, which demands the efforts in manufacturing R&D of upstream industries, measurement and characterization as well as product application of downstream industries. Hope the future of powder industry will be better and better.

Commonly Used Media and the Requirements for Particle Size Analyser

The commonly used liquid medium for particle sizing are water, anhydrous ethanol, and other organic solvents. For dry dispersion particle sizing, compressed air or compressed nitrogen are commonly used as gas medium. The main function of the medium is to homogenate the particles, so that the particle size test can be carried out smoothly. Liquid medium should meet the following requirements for particle sizing:

(1) High purity;
(2) No physical or chemical reactions with the particles;
(3) Good affinity with the particles, that is, a good wetting effect on the surface of the particles;
(4) Allow the particles have a proper suspension state;
(5) the temperature difference between the medium and the room temperature should be as small as possible to prevent the sample pool from fogging.

For dry dispersion particle sizing, the gas medium should be pure, dry, adjustable pressure, non-toxic, odorless, and cheap.

What is reproducibility? What Is the Difference Between Repeatability And Reproducibility?

Requirements for Dry Powder Sampling

The particle size measurement is a process of characterizing a small amount of sample to represent the whole batch of the product. Therefore, sampling is the first and also the most important step of particle sizing. Sampling means taking sample from a large pile of material for testing. The requirements for sampling are:

(1) Sampling dry powders from the powder stream instead of a pile of powders to make sure the sampling is representative;
(2) If has to sampling from a pile of powders, multipoint sampling (at least 4 points) with different depth must be taken and mixed together.
(3) Samples taken to the laboratory must be mixed evenly and then use a small spoon to take from at least four points, put into the instrument for dispersive testing.
(4) When sampling from a suspension, mix the suspension evenly with an electric mixer, take the sample from the center of the suspension, then add the sample into the instrument for particle sizing.
For special samples with high density, coarser size, and wide particle size distribution, add a very small amount of medium to form a paste, then take sample from the paste after mixed evenly.

Helium-Neon Laser for Particle Size Analyzer

Why Does a Particle Size Analyser Need to be Grounded?

"Grounding" gives the shell of instrument and the common port terminal zero potential. It has two functions:

(1) Improve the instrument stability by enhancing the ability of anti-interference;
(2) Ensure the safety of the operator. If the power supply in a lab does not have a ground wire, a temporary ground wire should be installed that connects directly to the earth/ground and the instrument shell or the power line of the instrument.

How to Determine Whether the Laser Particle Size Analyzer is Running Normally?

Background status could help to estimate whether the laser particle size analyzer is running normally. If the background value >4 or the column heights in the histogram are uneven, it indicates poor alignment. The background value <0.3 means laser brightness is down. If the background histogram is over 20 channels, it means the sample cell is not clean or foggy formed. If there are background signals at the right side of the co-ordinate, it is necessary to check whether the sample cell and the medium are clean. The background patterns from different particle size analyzer manufacturers may be different. However, they all work in the same way where the background are the signals received by the detectors at different angles after the laser passes through the sample cell with medium. The background patterns directly indicate whether the particle size instrument is running normally.

Basic Methods of Particle Dispersion

Particle agglomeration refers to the aggregation of multiple individual particles under certain conditions. Agglomerated particles are characterized by low binding force and instability. The agglomerated particles can be dispersed under external force but will aggregate again under suitable conditions. Aggregation is mainly caused by surface charges on the particles, moisture, and van der Waals force, etc. The smaller the particles, the greater the possibility of agglomeration because of their larger surface energy.

 

Laser Diffraction: A Powerful Particle Size Analysis Tool for Chocolate

Chocolate, first created by a pre-Olmec race in 1900 BC, subsequently used by the Mayans and Aztecs was passed to the chocolate houses by the Spanish across Europe after 3,500 years. The manufacturing process and final characteristics of chocolate are significantly affected by particle size in many ways. Lower production costs and better chocolate quality are desirable and achievable only with the help of high-performance laser diffraction instruments. Manufacturers are able to control particle size distribution of intermediates as well as final products in chocolate production in a highly efficient way.

Particle sizing of chocolate of different types

The cocoa liquor is blended back with the cocoa butter and other ingredients in varying quantities to make different types of chocolate including white, milk and dark chocolates of varying cocoa percentages. As shown in Table 1, dark chocolate contains either few or no milk solids whereas milk chocolate does contain powdered milk. White chocolate however contains no cocoa products at all, only cocoa butter and no chocolate solids, so in reality it is not technically a chocolate at all in the real sense.

Table 1.Principal ingredients in different types of chocolates (white, dark and milk chocolate)

The comparison of particle size distributions (PSD) of milk, dark and white chocolates of the same brand are achieved by the Bettersizer 2600 and shown in Figure 1. It can be seen that the mean size order is milk > dark > white chocolate. The change of the coarse end of the distribution indicates the change in the cocoa particles and milk solids content required. At the coarse end of the distribution, milk chocolate has a larger percentage than the other two kinds of chocolates. On the other hand, white chocolate has a greater percentage of fine particles at around 5 μm. Despite that, the bimodal nature of PSD could be observed on either chocolate due to the presence of multiple components in the chocolate.

Particle sizing of milk chocolate of different countries

Apart from particle size variations in the different types of chocolate, are there size differences in the chocolates of the same type but produced in different countries? The answer is yes. There is no standard recipe for chocolate production globally and there will always be regional differences in its production and the particle size will of course be different. We can imagine that in order to target local customers, the chocolate sold in different places should have various particular characteristics, appropriate for the local taste such as the particular melting temperature or the mouthfeel.

In the experiments below, five milk chocolate produced in different countries (China, Switzerland, America, UK, Belgium) were analyzed by the Bettersizer 2600 in order to investigate the regional customer preference on the mouthfeel and flavor of chocolate, which will in turn affect the manufacturing process as well as final particle size of chocolate.

A global comparison of PSD of milk chocolate was shown in Figure 2. Significant diversities were easily observed, and the mean size sequence of milk chocolate obtained is China > Switzerland > America > UK > Belgium. Critical particle size values (D10, D50 and D90) are shown in Table 2 where a similar trend can be observed. We can thereby speculate that milk chocolate coming from Belgium or UK has undergone a longer grinding and conching time, and probably required more cocoa butter or lecithin in the manufacturing process in order to maintain the flow properties because they contain finer particles than other milk chocolate.

Table 2.Critical values of particle size distribution of milk chocolate in different countries

In conclusion, the Bettersizer 2600 successfully performed the measurements of characterizing chocolate of different types (dark, milk, white) and various countries, and has therefore been proven to be an effective tool to analyze the particle size distribution of chocolate and help chocolate manufactures produce more attractive and consistent final products.

The Difference between Mie Scattering and Fraunhofer Diffraction Theory

Commonly Used Dispersants

A dispersant is a substance that significantly reduces the surface tension of the medium and hence improves the surface wetting or charged state of the particles. The dispersant could disperse particles and prevent them from aggregating. The commonly used dispersants in particle sizing include sodium hexametaphosphate and sodium pyrophosphate. Some specific dispersants can achieve better dispersion for special samples.

How to Measure Particle Shape?

Particle shape, also named as particle morphology, is currently characterized by measuring and calculating the projected shapes of the particles, including outline contour and roughness. All the methods employ microscopic imaging systems with the function of image analysis. In the calculation of particle shapes, the characterization of irregular shaped particles is common, with important features including particle roundness, the aspect ratio of elongated (or fibrous) particles, and the ratio of thickess-to- diameter for flakes or platelets, etc. The images are taken by microscope and then analyzed by software. The specific analysis methods are:
(1) Roundness: it can be calculated by the circumference of the circle equal to the particle area divided by the actual circumference of the particle (could also be calculated by "the equivalent diameter of the circumference is divided by the area equivalent diameter"). But no matter what algorithm is used , the closer the value is to 1, the better the roundness of the particles.
(2) Aspect ratio: the ratio of the length of the particle circumscribed rectangle to the average width of the particle.
(3) Diameter-thickness ratio: the ratio of the diameter of the particle-equivalent circle to the thickness of the particles.

  

What is the Best Range of Shading Ratio in Laser Particle Sizing ?

Shading ratio refers to the percentage of light scattered and absorbed by particles, which is used to represent the optical concentration of suspension in laser particle sizing.

Shading ratio = (I0 – Ii)/I0 x 100%. 'I0' is the original light intensity; 'Ii' is the light intensity at the detector center. Shading ratio is usually between the range of 10±5. In the actual particle size measurement, the best shading rate is the equilibrium point between the plural scattering and the representativeness. For this purpose, the optimal range of shading ratio is related to particle size. The larger the particles, the higher the shading ratio is. The common relationship between shading ratio and particle size is given below:

The Importance of Particle Shape

The properties of particles include particle size, shape, surface structure and pore structure. The shape of the particles can impact on many properties of a powder sample, inclding specific surface area, flowability, magnetic property, packing property, abrasive property and chemical activity. In order to improve the characteristics and performance of some products, particle shapes have been designed and produced based on their applications by industrial and scientific research. The table below shows the effects of particle shape on product performance:

What is the Function of SOP in Particle Sizing?

SOP is short for Standard Operation Program. It is now available in smart laser particle sizing instruments, facilitates operation automation and standardization, and is used to achieve 'one-click' operation.

SOP reduces the labor intensity, and, more importantly, standardizes the test conditions, minimizes the errors caused by different operators, and improves the reproducibility of the test results. Before applying SOP, the standard operation procedures should be set up, including the cycle cleaning times, dispersing time by ultrasonication, shading range of the sample, circulating speed, data storage, result printing, and automatic alignment, etc.
