- Conclusions:
- The average particle size of the Copper cyanide sample was 60.3 um after five times of particle size analysis by laser diffraction and scattering.
- Executive summary:
For this endpoint, an experimental study was available for the registered substance.
The particle size was measured using the Laser diffraction / scattering method according to KS A ISO 13320 : 2014.
The purpose of the study was to measure the particle size of Copper cyanide by a micro particle size analyzer using laser diffraction and scattering. Irradiated by particles, the intensity of the scattering of light and scattering of light is sensed by the detector, which reaches the particles of light, and thus calculates the size of the particles.
The average particle size of the Copper cyanide sample was 60.3 um after five times of particle size analysis by laser diffraction and scattering.
