PARTICLE CHARACTERIZATION

摘要

A method of measuring characteristics of particles in a liquid sample (10), comprises supporting the liquid sample by surface tension,illuminating the supported liquid sample along an illumination axis (16) with spatially coherent light so as to cause the coherent light to be scattered across a scattering zone, and detecting at least a portion of the scattered light along a first predetermined scattering detection axis (18) after it is scattered by the particles in the supported liquid sample, wherein the illumination axis (10) and the detection axis (18) are oriented at an angle with respect to each other that allows substantially all of the light scattered at that angle across the scattering zone to be detected.
