Gel permeation chromatography (GPC) - Part 3: Water as elution solvent

DIN 55672-3-2007 发布历史

This standard describes the determination of the molecular weight distribution, number-average molecular weight Mn and weight-average molecular weight Mw of polymers that are soluble in water by gel permeation chromatography (GPC). This standard is applicable to neutral polymers and polyanions (e.g. polycarboxylates, polysaccharides, completely saponified polyvinyl alcohols and high-molecular polyethylene oxides). It is not applicable to polycations (e.g. polyvinytpyrrolidone, polyvinylpyridine, salts of poly(diallyI-N,N-dimethyl-azacyclopentane) and chitosane. It is possible that, in spite of the good solubility in the mobile phase and the good repeatability of the chromatograms obtained, this method cannot be used with certain polymer types because of specific interactions, such as adsorption, within the sample/eluent/column combination (see also clause 12). The method is not an absolute one and requires calibration with commercially available unbranched pullulan standards that have been characterized by independent absolute methods. The results for samples of polymers other than pullulan are therefore only comparable within groups of samples of the same type. The conditions specified in this standard are not suitable for the GPC analysis of polymer samples with Mw values greater than 10~6 g/mol (see Annex C). No correction methods (e.g. for the elimination of peak broadening) are included in this standard. If absolute molecular weight values are required, an absolute method, e.g. membrane osmometry for Mn or light scattering for Mw, shall be used.
