Calibration Standards for SEC (GPC & GFC)

· For organic solvent SEC (GPC) · Less branched polystyrene with anionic polymerization · Easily soluble in tetrahydrofuran (THF), chloroform, toluene, and o-dichlorobenzene (ODCB)
M-75 · For organic solvent SEC (GPC) · Narrow molecular weight distribution range · Easily soluble in hexafluoroisopropanol (HFIP) and dimethylformamide (DMF)
P-Series · For aqueous SEC (GFC) · Unbranched   pullulan standard · High solubility in water eliminates the possibility of   recrystallization · Please note recently discontinued products from P-Series   [P-1, P-2, P-3, P-1300, P-2500 no longer available]
