Particle size analyses

Integrated optical system allows measurement of particle size and particle characterization analyses of materials in a single size range from 0.02 to 2000µ with no lens changes or setting changes.
When working with fine particles it is often found that particles segregate by size when they are agitated or shaken, this is a main principle of particle size and particle characterization analyses. Therefore when samples are obtained it is important to know whether or not this process has occurred. If segregation does occur, then the results of particle size, particle shape, surface area (BET), poresize & volume, porosity, density (true density, skeleton density & tab density) measurements can be severely altered and give the results of particle size and particle characterization analyses. In industrial applications if segregation occurs, entire processes can fail to achieve their desired end results. Among more modern techniques, the conventional techniques such as gravitational sedimentation and sive analysis are available to analyse particle size and particle characterization. Soil samples are measured with the sedigraph from micromeritics. sive analysis is made by retsch. The stokes sedimentation gives the settling rate thus the sedimentation diameter.
The particle size distribution resulting from a particle size analysis from a dispersion by gravitational sedimentation gives a good result. With sedimentation from soil the sedigraph made by micromeritics is a very good instrument. Sieving with retsch sive analysis is an old technique. The stokes sedimentation uses the settling rate giving the sedimentation diameter. In this way the size distribution can be compared to sieving. In gravitational sedimentation (originally the pipette method) the settling rate of particles in liquid is measured and related to the mass by use of the Stokes law. Nowadays the settling rate is determined by measuring x-ray transmission in the liquid at specific heights and time intervals and a size distribution based on difference in mass is calculated.
The gravitational sedimentation is suitable for any material containing elements with Z > 12 and is popular for determination of clay fractions in soil samples. The sizing range, determined by laminar flow, is from 1 to 300 µm. The gravitational sedimentation measurements are performed on a Micromeritics Sedigraph 5100 and the report consists of a graph showing the cumulative and differential mass distribution and statistics as the mode, mean and median diameter, standard deviation etc.
Micromeritics products, with a few exceptions, do not require calibration per se; they derive results from well-established laws utilizing detection of basic parameters such as time, temperature, pressure, mass, and the like in order to perform particle size and particle characterization measurements.
