- Conclusions:
- The test was conducted to BS ISO 13320-1 : 1999.
The D95 was determined in average between 7.3 and 1410 μm - Executive summary:
The test is conducted to determine the particle size distribution of Phytosphingosine. The sample is initially observed to determine whether sieving of the material is required. The final sample is then analysed using the Coulter Laser Diffraction Analyser fitted with a dry powder module. It is normal practice to complete 3 runs to ensure repeatability of results.
The test was conducted to BS ISO 13320-1 : 1999.
The D95 was determined in average between 7.3 and 1410 μm
