ISO/TS 21362:2018 is a technical specification that provides guidance on analyzing nano-objects using asymmetrical-flow and centrifugal field-flow fractionation (AF4 and CF4). It outlines parameters and conditions for developing and validating methods for these techniques. The standard is part of an integrated measurement system for analyzing nano-objects, their aggregates, and agglomerates in aqueous media.
