System Configuration

Wet measurement for small amount of sample / Almost all dispersion media can be used. Measurement without Dilution
Batch Cell SALD-BC23 High-Concentration Sample Measurement System SALD-HC23S
Funnel ・ Measures using small quantities of samples (particles being measured) and liquid
media (dispersion media). ・ High-concentration samples can be measured using the laser diffraction method.
・ Organic solvents or acids can be used. ・ Measurement is possible by simply holding the high-concentration sample particles between two glass slides.
・ Less liquid waste is disposed of when using suspensions containing organic solvents ・ Samples for which the particle size distribution would be changed by dilution can be measured in their original state, or with the minimum required level of

If a standard flow cell or batch cell is used to measure a sample at a high concentration, the long light path length results in multiple scattering,
making it impossible to obtain accurate measurements.
