How to Diagnose GC Septum Bleed Contamination – Restek The bleed from either septum shows a similar pattern (Figure 1), but it is easy to determine the source with a simple test. Isolate the inlet by setting the instrument to perform a run without an injection. Perform an analysis; if the bleed disappears, then the vial cap septum was the source. Determining if the vial cap septum is the source of Controlling Contamination in LC/MS – Waters Corporation • Self-sealing septa cont...

Prevent GC Inlet Problems BEFORE They Cost You Time and Money GC Septa. The GC septum should be routinely replaced to reduce the risk of leaks and septum particle contamination. In fact, if the instrument is in heavy use, change the septum daily. Repeated use of the same septum will result in increased coring, which may introduce a leak and/or result in septum fragments being deposited in the inlet liner.
