selection guide Overview Diferent septa material for LC and GC applications There are many diferent types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa
make PTFE/silicone septa suitable for all types of chromatographic applications. A thin film of PTFE is laminated to the side of the septum that faces the sample to limit exposure of the elastomer to the solvent. PTFE/Silicone septa are ideal for use in most HPLC and GC applications where resealability and purity are critical.
