LS-C(III) Dry & Wet Dispersion Particle Size Analyzer
Application: The dry dispersion mode can be used to measure the samples that can’t be dispersed in liquid but in air, the wet dispersion mode can be used to measure the samples dispersed in liquid.
Principle: Uses the principle of laser light scattering to determine particle size distribution. OMEC’s instruments own the advantages of wide measurement range, good repeatability, simple operation and etc. through OMEC’s system integration and optimization for optics, mechanics, electronics and computer.
Report Items: Particle size distribution table, particle size distribution curve, median diameter, Characteristic particle size, width coefficient, SSA, industrial segmented percentage of particles, > 80μm percentage (fineness), other synthesis parameters of particle size , etc.
