Pullulan (Polysaccharide) Standards
Shodex STANDARD Pullulan Series is a calibration standard for aqueous Size Exclusion Chromatography. Pullulan is a Polysaccharide with units of Maltotriose are bonded with alpha-1,6 connection, and its chains are linear without branched chains. The sample solution of this standard is easy to prepare and easy to handle, because it is stable without agglomeration, crystallization or electrical-charge, and moreover Pullulan is not adsorbed to column packing materials. This is good as molecular weight standard to make calibration for Size Exclusion Chromatography (SEC).
