Scope

This part of GB/T 36214 specifies a general test method for determining the average molecular weight and its distribution of polymers using SEC-LS (that is, size exclusion chromatography coupled with a light scattering detector). The average molecular weight and molecular weight distribution are calculated by continuously measuring the molecular weight and mass concentration during the elution time. The molecular weight at each elution time is directly measured by a light scattering detector coupled with a concentration-sensitive detector, so SEC-LS is an absolute method.
The application of this method is described in A.1 of GB/T 36214.1-2018.
