Gel permeation chromatography (GPC) - Tetrahydrofuran (THF) as eluent Ingestion-build-228203 Why should you use ISO1 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 tetrahydrofuran (THF) by gel permeation chromatography (GPC). NOTE Also known as size exclusion chromatography (SEC). Even though the chromatograms obtained show good repeatability, it is possible that this method cannot be used with certain polymer types because
