Gel Permeation Chromatography

Find out about our Size Exclusion Chromatography service, (formerly known as Gel Permeation Chromatography).


We provide Size Exclusion Chromatography (formerly known as Gel Permeation Chromatography, GPC) that measures the distribution of molecular masses in a polymer.

The instrument is a 1260 GPC/SEC MDS from Agilent, equipped with:

  • triple detection: differential refractive index, viscometer and dual angle light scattering
  • two columns PLgel 5 µm MIXED-D 300 x 7.5 mm (with a guard column PLgel 5 µm MIXED Guard 50 x 7.5 mm)
  • tetrahydrofuran (THF) as mobile phase
  • columns and detectors all maintained at 35°C
  • calibration using a set of polystyrene or poly(methyl methacrylate) (PMMA) standards
