Because gas-tight syringe samplers inject through the GC injection port septum,ensure the septum is well maintained to decrease the possibility of a leak. For balanced-pressure sampling instruments,analysts should consider the inertness and efficiency of the components that make up the sample pathway inside the autosampler.
