Gel permeation chromatography (GPC) — Part 3: Water as eluent
This standard specifies the requirements for determining the molecular weight distribution of water-soluble polymers by size-exclusion chromatography using water as the eluent. It is applicable to the characterization of polymers with a broad range of molecular weights, including those used in paints, coatings, and related industries. The method involves the use of specific separation columns, calibration techniques, and data analysis procedures to ensure accurate and consistent results. This standard is particularly useful for quality control, research and development, and production processes where polymer molecular weight distribution is a critical parameter.
