H2S in gas sample

[tolisfoto]

I have to make injections in porapakQ-TCD with a sample with CO2, CH4, H2, and it maybe contains small quantities of H2S. Is H2S poisonous for porapakQ column or TCD? which temperature must I set the column for H2S to elute?

tolisfoto,

H2S will be OK on a PorapakQ column and a TCD. An old Chrompak application shows on a 9 Ft PorapakQ column at 50'C, and helium carrier gas at 30 ml/min, CO2 has a RT of 1.5 mins and H2S has 5.2 mins.
