Determination of particle size distribution by gravitational liquid sedimentation methods — Part 5: ...
This part of ISO 13317 describes and principles and proper use of gravitational photosedimentation techniques for the characterisation of dispersed phases of suspensions and emulsions. These techniques monitor the gravity-induced phase separation of particulate materials dispersed in liquids by recording photometric signals (i.e., intensity of transmitted or scattered light) as function of…
