ATS chemists use Light Scattering (also known as Laser Diffraction) to take a simple measurement of the particles in a powder sample. Our particle analyzer cycles the specimen through the path of a laser beam. By recording the angle and intensity of the light scattered when it hits a given particle, the equipment’s processor can apply an algorithm to calculate the diameter of that particle. Performing this process several thousand times in seconds yields data that our powder characterization specialists can use to determine the range of sizes present in the sample, called the particle size distribution
. Our chemists conduct this method to ASTM D4464, ASTM B822, and ISO 13320.
