These units measure the particle size distribution of a sample powder dispersed in the air.
Use these units for particle size distribution measurements of powders with no suitable dispersion medium and powders that dissolve in liquids.
Two unit types are available, to suit the sample state and measurement aim.
SALD-DS21 Injection type Dry Measurement Unit (measuring range: approx. 0.8 to 1000um) (P/N 347-60100-20)
Sample powder is dispersed for measurement by injecting in the air from a nozzle.
The unit offers three types of sample suction mechanism and three types of nozzle, which allow setting of the optimal dispersion force and sample volume conditions to match the sample state and aim of measurement.
SALD-DS3 Free-fall type Dry Measurement Unit (measuring range: approx. 10 to 3000um) (P/N 346-61206-10)
The sample is measured during free fall.
Even easily damaged particles can be directly measured,
A separate dry-measurement detector case (P/N 347-60010-20)
compressor (SALD-DS21 only) and dust collector are required to use the dry measurement units.
SALD-AC30 Acyclic Motion Sampler (P/N 346-83746-02)
Completes one measurement cycle in 30 seconds, Including washing. Automatically detects sample infuse to start measurement and data storage. The rapid measurement time saves effort and makes this the optimal unit for measuring samples with a rapidly changing particle size distribution, such as powder undergoing a grinding process.
Example of Particle Size Distribution of Corn Starch (dry measurement)
2. Example of Particle Size Distribution of Flour (dry measurement)
Measurement of the particle size distribution of these sands was attempted on the SALD-3000. As expected, it was found that "Sun sand" is slightly larger than "Star sand."
