Full Description

ISO 16014-4:2003 specifies a method for determining the average molecular mass and the molecular mass distribution of polymers by size-exclusion chromatography (SEC) using an organic eluent at temperatures between 60 C and 180 C. The average molecular mass and the molecular mass distribution are calculated from a calibration curve constructed using polymer standards. Therefore this method is classified as a relative method.
