Scope

This document provides guidance on using dynamic light scattering (DLS) technology for measurements and interpreting the results. It includes information on how to prepare samples in an appropriate manner, how to verify that the instrument is operating normally, and how to correctly interpret the data (including methods for assessing data quality), which goes beyond the guidance on measurements provided in GB/T 29022-2021.
This document is suitable for assisting users in planning experiments for measuring solid particles, emulsions, and bubbles. It particularly focuses on how to obtain the necessary information about the samples and determine whether DLS is the most suitable detection method. The emphasis is on the practical steps required to obtain high-quality DLS measurement results, rather than theoretical discussions.
