Polystyrene

  • For organic solvent SEC
  • Less branched polystyrene with anionic polymerization
  • Easily soluble in tetrahydrofuran (THF), chloroform, toluene, and o-dichlorobenzene (ODCB)

Polymethylmethacrylate (PMMA)

  • For organic solvent SEC
  • Narrow molecular weight distribution range
  • Easily soluble in hexafluoroisopropanol (HFIP) and dimethylformamide (DMF)

Pullulan

  • For aqueous SEC
  • Unbranched pullulan standard
  • High solubility in water eliminates the possibility of recrystallization

The molecular weights (Mp, Mw/Mn) of each standard kit may vary depending on production lots.
