Determination of polymer by plastic volume exclusion chromatography
Average molecular weight and molecular weight distribution
Part 1. General
1 Scope
This part of GB/T 36214 specifies the determination of the average molecular weight and molecular weight distribution of polymers using volume exclusion chromatography (SEC).
General method. The average molecular weight and molecular weight distribution are calculated from the calibration curve. The calibration curve is either by GB/T 36214.2~
Calculated from the polymer standard of one of the SEC techniques described in GB/T 36214.4, or equipped with light scattering detection as described in GB/T 36214.5
The absolute molecular weight data of the volume exclusion chromatography (SEC-LS) of the detector was calculated.

3 Terms and definitions
The following terms and definitions defined by ISO 472 apply to this document.
3.1
Volume exclusion chromatography size-exclusionchromatography; SEC
The hydrodynamics of molecules eluted in a column packed with a non-absorbent porous material with a pore size similar to the size of the molecule being separated
A liquid chromatography with a volume based on separation.
Note. The term gel permeation chromatography (GPC) should be used only when the non-absorbent porous filler material is a gel; however, volume exclusion chromatography (SEC) terminology
It is preferred.
3.2
Light scattering detection light-scatteringdetection
LS detection
A technique for determining the quality or size of a polymer molecule by measuring its light scattering.
