Pullulan calibration standard
- Kit STANDARD P-82 with 8 different MW
- Water-soluble unbranched polysaccharide calibration kit for aqueous SEC
- Pullulan is a linear polysaccharide composed of maltotriose units connected by α-1,6 bonds, offering stability without agglomeration, crystallization, or electrical charge.
Polystyrene (PS)
- Available as three different kits for low, medium and high MW:
STANDARD SL-105, SM-105, SH-75 - Molecular weights ranging from 4 to 200,000.
- Easily soluble in tetrahydrofuran (THF), chloroform, toluene, and o-dichlorobenzene (ODCB) and are used for organic solvent SEC (GPC).
- The polystyrene is less branched, synthesized through anionic polymerization.
Polymethylmethacrylate (PMMA)
- Kit STANDARD M-75 with 7 different MW
- Suitable for use with hexafluoroisopropanol (HFIP) and dimethylformamide (DMF) solvents, as well as tetrahydrofuran (THF), toluene, methyl ethyl ketone, ethyl acetate, DMF, and DMAc
- Designed for organic solvent SEC (GPC) and features a narrow molecular weight distribution range.
