GPC Standards Kit

Pharmacosmos supplies a kit of 10 well-characterized GPC standards for universal calibration, calibration of aqueous GPC chromatography systems and molecular weight determination.

Each GPC standard has been characterized analytically by means of:

  • Low Angle Laser Light Scattering (LALLS)
  • Reducing End Group Titration (EGT)
  • Gel permeation chromatography (GPC)
  • Viscosity measurement at 25°C (Visc.)

The molecular weight specifications for all GPC standards are provided in the following tables, i.e.:

  • Number average molecular weight Mn
  • Weight average molecular weight Mw
  • Mean peak molecular weight Mp
  • Polydispersity Mw/ Mn

In addition, the GPC standards are supplied with differential and integral molecular weight distributions in both graphical and tabular forms.
