Determination of particle size distribution by centrifugal liquid sedimentation methods - Part 1: General principles, requirements and guidance
This document specifies the principles of particle size analysis by centrifugal liquid sedimentation (CLS).
It also:
An important part of this document deals with the derivation of particle size distributions from CLS data, including discussions on:
This document applies to samples composed of dispersions of low particle concentration, so that the particlesβ motion can be considered as that of fully isolated particles.
This document does not cover particle migration by gravity, electric or magnetic forces.
It also does not cover deriving particle properties other than size, sedimentation velocity and sedimentation coefficient.
NOTE This document can involve hazardous materials, operations and equipment.
It does not purport to address all the safety problems associated with its use.
Regulations regarding explosion-proof analysers can apply when examining volatile liquids with a low flash point.
It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of the regulatory limitations prior to its use.
