Gel permeation chromatography (GPC) - Water as eluent Ingestion-build-96603 — marine organisms capable of1 Scope This document specifies the determination of the molar mass distribution and the average molar mass values Mn (number average) and Mw (weight average) of polymers that are soluble in water by gel permeation chromatography (GPC). NOTE Also known as size exclusion chromatography (SEC). This method is applicable to neutral polymers and polyanions (e. g. polycarboxylates, polysaccharides, fully hydrolyzed polyvinyl alcohols and high molecular
