Calibration Standards for SEC (GPC & GFC)
[Polystyrene (PS)][Polymethylmethacrylate (PMMA)][Pullulan]| SL-105 SM-105 SH-75 | · 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] |
