- Principles of method if other than guideline:
- During the laser diffraction measurement, particles were passed through a focused
laser beam. These particles scattered light at an angle that was inversely proportional to their
size. The angular intensity of the scattered light was then measured by a series of
photosensitive detectors. The number and positioning of these detectors has been optimized
in this model of apparatus to achieve maximum resolution across a broad range of sizes.
This apparatus in dry dispersion method uses a single wavelength detection system:
A red-light measurement with a Helium-Neon laser is used. - GLP compliance:
