Scope

This part of ISO 16014 specifies a general method for determining the average molecular mass and the molecular mass distribution of polymers using size-exclusion chromatography (SEC). The average molecular mass and the molecular mass distribution are calculated from a calibration curve constructed using polymer standards if using one of the SEC techniques described in Parts 2 to 4 of this International Standard or from a calibration curve constructed using absolute molecular mass data if using size-exclusion chromatography coupled with light-scattering detection (SEC-LS) as described in Part 5 of this International Standard. The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. polymers using size-exclusion chromatography — Part 2: Universal calibration method using size-exclusion chromatography — Part 3: Low-temperature method using size-exclusion chromatography — Part 4: High-temperature method polymers using size-exclusion chromatography — Part 5: Method using light-scattering detection 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 472 and the following apply. 3.1 size-exclusion chromatography SEC a liquid chromatographic technique in which the separation is based on the hydrodynamic volume of molecules eluting in a column packed with porous non-adsorbing material having pore dimensions that are similar in size to the molecules being separated NOTE The term gel permeation chromatography (GPC) should only be used where the porous non-adsorbing packing material is a gel; however, the term size-exclusion chromatography (SEC) is preferred. 1
