- 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 Helin Findik and make the order through PPMS.
The DLS is a Nano ZS from Malvern.
It is located in MXD 137.
If you want a training, please request it on PPMS.
