Broad Range Molecular Weight Standards

Broad range molecular weight standards contain homopolymers with a broad molar mass distribution. These standards are available for a variety of polymers, including polystyrene, polymethylmethacrylate (PMMA), and polyvinyl pyrrolidone. Broad standards can be used for GPC/SEC column calibration, to validate chromatographic systems and detectors, and to determine physical constants such as the Mark-Houwink constants K and α.
