- 36.04 % of particles own a diameter over 200 μm. - Executive summary:
A study was performed to determine the Particle Size Distribution of the test item P-MENTHANE-1,8-DIOL. The method followed was designed to be compliant with the Guideline ISO 13320. (2020). Particle size analysis – Laser Diffraction methods.
In this method, the particle size distribution (PSD) is determined using a laser diffraction granulometer.
The laser diffraction technique for the determination of PSD is based on the phenomenon that particles scatter light in all directions with an intensity pattern that is dependent of particle size. This light pattern is recorded with captors placed in the laser diffraction granulometer.Using an optical microscope (x 100 magnification), the substance was visually confirmed as being a crystalline powder, not a fibre.
Four measurements were performed using dry way.
The following results were obtained from the mean of measurements 2, 3 and 4:
This particle size distribution has the following properties:
Per cent of particles with diameter ≤ 2 μm: 0 %
Per cent of particles with 2 μm ≤ diameter ≤ 200μm: 63.96 %
Per cent of particles with diameter ≥ 200 μm: 36.04 %
The following table summarizes the cumulative distribution between 2 μm and 200 μm:Diameter (μm) 2.0
10.1 22.8 34.3 44.9 59.0 77.3 101.5 152.5 200.0 Cumulative percentage of particles (%) 0.00 0.00 1.57 5.32 10.98 19.92 31.36 42.99 56.75 63.96 Moreover the particle size distribution deconvolution in two peaks gives the following data:
