PD ISO/TR 22814:2020

What is ISO/TR 17534-4 about?

ISO/TR 22814 provides practical guidance for performing and interpreting measurements using dynamic light scattering (DLS) that goes beyond the treatment of measurement artifacts. ISO/TR 22814 is intended to help users with experiments planning, in particular with respect to obtaining the necessary information on the sample and deciding whether DLS is the most appropriate method. ISO/TR 22814 provides information on how to prepare samples in an appropriate way, verify the proper functioning of the instrument, and interpret the data correctly, including ways to assess data quality. ISO/TR 22814 focuses on the practical steps required to obtain DLS results of excellent quality, rather than on theoretical considerations, and covers not only the measurement of solid particles but also emulsions and bubbles.
