Standard Test Method for Determining Molecular Weight Distribution and Molecular Weight Averages of Polyolefins by High Temperature Gel Permeation ChromatographyMore info
1.1 This test method covers the determination of molecular weight distributions and molecular weight averages of linear polyolefins by high temperature gel permeation chromatography (GPC). This test method uses commercially available polystyrene standards and equipment and is applicable to polyethylenes (excluding high pressure low density polyethylene–LDPE) and polypropylenes soluble in 1,2,4-trichlorobenzene (TCB) at 140°C. This test method is not absolute and requires calibration.
Note 1—Size exclusion chromatography (SEC) often is used as an alternative name for gel permeation chromatography (GPC).
