Molecular Weight Reference Polymers

PSS is one of the world‘s largest manufacturers of reference polymers copolymers, and customer-designed polymers. A great selection of polymer types in a wide range of molar masses is produced regularly like polystyrene, polymethylmethacrylate, polyethyleneglycol, dextran, pullulan, polylactides, polyacrylic acids, polyvinylpyridines, polyolefins, and others.

The PSS reference materials are characterized extensively by modern analytical methods. They are available in various characterization levels: GPC, DIN Certified Standards, MALDI validation standards, Light Scattering, Viscometry and Certified Reference Materials. Their suitability for a given application depends on the polydispersity, or the level of characterization. Reference polymers come as individual standards or assembled into kits including ReadyCal calibration kits for fast calibration of GPC/SEC systems and validation kits for the validation of instruments and detectors.

The kit components are carefully selected to cover given molecular weight ranges to establish calibration curves.
