Description
General description
PTFE-fused septa are suitable to overcome the degradation, which happens due to prolonged high temperatures, commonly observed in silicone rubber septa. The degradation results in baseline drift and additional peaks. It is generally fixed with the PTFE face towards the column packing.
Application
PTFE-faced butyl septa may be used for headspace vials to assess sampling efficiency and breakthrough of methyl bromide on activated charcoal.
Septum may be used to seal vial during collecting urine samples for unmodified benzene analysis using HPLC method.
