and
Powder Properties Powders are collections of particles distinct from solids and liquids; they have properties and
exhibit behaviors that would put them somewhere between solids and liquids. For this reason,
measurement of particle size distribution, specific surface area, and pore distribution is usually
performed using instruments specifically for the evaluation of the surface properties of powders.

•Laser Diffraction Particle Size Analyzer SALD-3100
[Model for Analyzing Coarse and High-density Particles]
Measurement range: 0.05 to 3,000 µm
Light source: Red semiconductor laser (wavelength: 690 nm)
The sampler is equipped with a powerful pump that ensures the reliable circulation of coarse and high-density particles, making this analyzer
suitable for the particle distribution analysis of soil and sand. It is ideal for research into environmental problems and measures for disaster
prevention.

•Laser Diffraction Particle Size Analyzer SALD-2100
[SALD-series Standard Model]
Measurement range: 0.03 to 1,000 µm
Light source: Red semiconductor laser (wavelength: 680 nm)
The successor to the SALD-2000 Series, which has proved to be one of the most popular product lineups in this field. Consistency and
compatibility with the SALD-2000 Series was given high priority in its development.

•Laser Diffraction Particle Size Analyzer SALD-7000
[Model for Analyzing Ultrafine Particles]
Measurement range: 0.015 to 500 µm
Light source: Blue-violet semiconductor laser (wavelength: 405 nm)
Performs accurate measurement of ultrafine particles using laser diffraction and scattering. It is a wet-type instrument that reliably captures blue
and black fine/ultrafine particles, a task that was difficult with earlier methods.
