Abstract: A comparison of septum degradation data obtained from a variety of standard GC septa, including the Thermogreen LB-2, AG3 (Green), Thermolite, BTO and the Merlin Microseal were evaluated. This study was conducted to determine analytical system lifetime between inlet maintenance based on chromatographic performance of reactive compounds as a function of septum aging through repeated injections. It is widely accepted that gas chromatographic septa degrade relative to the operating temperature of the injector and…
