Syringe Selection Assist
What is the operating temperature? Please choose below. (GC/MS, Autosampler)
Take note:
Low-bleed septum is not completely free of bleeding.
The type of bleeding that occurs varies with the septum, and results in different patterns on chromatograms.
In the case of high-sensitivity analysis, it is necessary to select a septum whose bleeding will not occur at a point that interferes with the peak of the target compound.
Conditioning for several hours between 120°C and 200°C after extraction with hexane may help to reduce bleeding.
In the case of using a syringe for AOC, it is recommended to exchange the septum after about 100 injections. If the outside diameter of a needle of a gastight syringe is thick, it is recommended to exchange after about 50 injection
Please note that difference in septum materials may affect analytical results when analyzing delicated samples such as pesticides with GCMS.
