Sizes and size distributions of macromolecules and particles

  • Gel Permeation Chromatography / Size Exclusion Chromatography (GPC/SEC)
The platform offers three different GPCs. They are located in LP.

Name Eluent Detector
Agilent 390-MDS THF RI, Viscometer, Dual-Angle Light Scattering
PSS-Polymer SECcurity² DMAc + 0.1 %w/w LiBr

RI, UV, Viscometer, Multi-Angle Light Scattering

If you need GPC measurements, please contact Yann Lavanchy.


The DLS is a Nano ZS from Malvern.

It is located in MXD 137.

If you want a training, please request it on PPMS.
