颗粒尺寸分析 动态光散射（DLS

[中文适用范围]： 本文件规定了动态光散射（DLS）技术在以下方面的应用：——测量平均水动力粒子尺寸；——测量主要为亚微米级颗粒、乳液或分散在液体中的微小气泡的尺寸分布。本文件适用于稀释和浓稠悬浮液的广泛测量。 [外文原描述]： This document specifies the application of dynamic light scattering (DLS) to the following: — measurement of average hydrodynamic particle size; — measurement of the size distribution of mainly sub micrometre-sized particles, emulsions or fine bubbles dispersed in liquids. This document is applicable to the measurement of a broad range of dilute and concentrated suspensions.
