Pharmacosmos GPC Standards provide a unique collection of 10 GPC standards (Gel Permeation Chromatography standards) for molecular weight determination. The GPC standards cover a molecular weight range from 1,000 Daltons to 670,000 Daltons.
The GPC standards are delivered with a complete set of specifications including weight average molecular weight Mw, number average molecular weight Mn, and mean peak molecular weight Mp. Differential and integral molecular weight distributions are provided in both graphical and tabular form (please see below).
