ISO 22412:2008规定了一种应用动态光散射（DLS）估算平均粒径和测量主要分散在液体中的亚微米级颗粒或液滴粒径分布宽度的方法。ISO 22412:2008适用于各种稀释和浓缩悬浮液的测量。DLS的原理与稀释分散体的原理相同。然而，需要对仪器设置和试样制备规范的具体要求，以及对浓缩分散测量结果的正确解释的一些建议。

ISO 22412:2008 specifies a method for the application of dynamic light scattering (DLS) to the estimation of an average particle size and the measurement of the broadness of the size distribution of mainly submicrometre-sized particles or droplets dispersed in liquids.ISO 22412:2008 is applicable to the measurement of a broad range of dilute and concentrated suspensions. The principle of DLS is the same as for a dilute dispersion. However, specific requirements for the instrument set-up and specification of test sample preparation, as well as some advice on the correct interpretation of the results of measurements for concentrated dispersions, are required.
