What is a Camsizer?

The CAMSIZER X2 is a powerful, extremely versatile particle size and shape analyzer with a wide measuring range that combines state-of-the-art camera technology with flexible dispersion options.

What is dynamic image analysis?

Dynamic Image Analysis (DIA) is a modern particle characterization method for the determination of size distributions and shape parameters. It allows quick analyses with excellent accuracy and reproducibility over an extremely wide measuring range.

How do you do particle size analysis?

The most common techniques to determine particle size distribution are dynamic image analysis (DIA), static laser light scattering (SLS, also called laser diffraction), dynamic light scattering (DLS) and sieve analysis.

What are the 2 types of particle size analysis?

Two of the most used techniques used for the particle size characterization of minerals are sieving and laser diffraction.

What is the principle of particle size analysis?

It works on the principle that when a beam of light (a laser) is scattered by a group of particles, the angle of light scattering is inversely proportional to particle size (ie. the smaller the particle size, the larger the angle of light scattering).

What are different methods for determining particle size?

Common methods of particle size measurement

• Sieves. While this is an old technique, it has the advantage of being cheap and particularly useful for the measurement of large particles.
• Sedimentation. This has been a common method used (historically) in clay and ceramics industries.
• Electrozone testing.
• Laser Diffraction.

What is particle characterization?

Particle characterization is the process of identifying the particle size, particle shape, and surface properties. Analyzing particle behavior is a critical factor for quality control and product performance in many different industries.

What is the basic principle of particle size analysis?

Why is particle characterization important?

To achieve high-quality pharmaceutical product, it is important to characterize the drug particles and understand the behavior of bulk powder. It is well known that particle characterization is an important consideration when ensuring optimal product development and efficient manufacturing within the pharma industry.

What is particle size D90?

D90: The portion of particles with diameters below this value is 90%. Volume percentage: The highest volume percentage of the particle size distribution displayed.

What is D value and D50?

For example, the D10 diameter is the diameter at which 10% of a sample’s mass is comprised of smaller particles, and the D50 is the diameter at which 50% of a sample’s mass is comprised of smaller particles. The D50 is also known as the “mass median diameter” as it divides the sample equally by mass.

What is coefficient of uniformity?

uniformity coefficient (u-ni-form’-i-ty). A numerical expression of the variety in particle sizes in mixed natural soils, defined as the ratio of the sieve size through which 60% (by weight) of the material passes to the sieve size that allows 10% of the material to pass.

What is D90 in PSD?

What is d10 d50 and D90?

d10, d50 and d90 are so-called percentile values. These are statistical parameters that can be read directly from the cumulative particle size distribution. They indicate the size below which 10%, 50% or 90% of all particles are found.

What is coefficient of uniformity and curvature?

Grain size analysis using sieves is a laboratory method to analyse the particle size distribution of the soil particles. The different sizes of sieves used are 80 mm, 40 mm, 20 mm, 10 mm, 4.75 mm, 2.36 mm, 1.18 mm, 0.6 mm, 0.3 mm and 0.15 mm.

What is the difference between coefficient of uniformity and coefficient of curvature?

The coefficient of uniformity or the CU is the ratio of the D60 by D10, if the ratio is greater than 4, then the soil is considered as good quality soil. But if the ratio is less than 4 then the soil is considered as bad quality soil. On the other hand, the coefficient of curvature is the ratio of (D30)2/(D10.

What is a CAMSIZER?

The CAMSIZER is a compact laboratory instrument fo… The CAMSIZER is a compact laboratory instrument for simultaneous measurement of particle size distribution and particle shape, number and density of powders and granules.

What is the difference between the CAMSIZER and the CAMSIZER XT?

CAMSIZER and CAMSIZER XT are both based on the proven patented 2-camera system. Whereas the CAMSIZER is optimized for the analysis of coarser, free flowing particles in the range from 30 µm to 30 mm, the CAMSIZER XT specializes in the analysis of fine, cohesive powders from 1 µm to 3 mm.

What accessories are available for the CAMSIZER?

Retsch technology offers a comprehensive range of accessories for the CAMSIZER in order to meet the individual requirements for each application. the individual components are selected according to the sample material properties. Feed hoppers Different hopper sizes are available for different amounts of sample.

How can the CAMSIZER be recalibrated?

By using a high precision reference object made by electron lithography, which simulates differently sized particles, the CAMSIZER can be recalibrated in a few seconds at any time. This means that the requirements of modern test agent monitoring are fulfilled.
