Wide applicability High resolution Accurately detects particle size distribution with five peaks

■ Using the SALD-MS23 sampler, the measurement range is 17nm to 2500µm for wet measurement. Scattered light from coarse particles is concentrated at low angles near the optical axis and fluctuates vigorously within a tiny angle, but scattered
For example, PSL particles with a median diameter of 50nm and stainless balls with a diameter of 2mm can be measured by a light from microparticles fluctuates slowly up to large angles away from the center. Whereas the intensity of scattered light from coarse particles

particle sizes by utilizing the relationship between particle size and scattered light and increasing the detection surface area of each of the 78
