TCD filament for corrosive gas analysis
Posted: Wed Jun 10, 2020 5:46 am
Hi
There is a question about corrosion of TCD filament with a gas containing 30% H2S. the GC system is a RGA and there are four H2S-rich samples per week. is the typical tungsten filament suitable for this system? or it requires another filaments like nickel or Gold coated ones?
Thanks
