This page shows a typical example of a Gel Permeation Chromatography (GPC) System configuration.
A differential refractive index detector, which offers comparatively uniform mass sensitivity, is used as the GPC detector.
PEEK tubing s often used as the connections for reverse-phase analysis. However, stainless-steel tubing is used for gel permeation chromatography of synthetic polymers. This is because stainless-steel tubes are more corrosion-resistant to THF eluent under high pressure than PEEK tubes.
**The model to the right for the SIL should read: SIL-20AHT
