H2S in LPG

Hi ..
Actually, i am looking for a method for the H2S in LPG rather the current one used which is the EXXON NO. 200.14 .
Any recommendation is appreciated.

alchemist,
H2S has an ionization potential of 10.45 so it is probably doable by PID (need an argon lamp?) or argon ionization detector if you get decent separation. Methane does not respond or responds poorly with an argon ionization detector so this helps you somewhat. You can always use an FPD but this can be an expensive option if you are not already equipped with one. I know differential mobility is an option but would be very expensive.
I would suggest a thick film -1 or -5 or perhaps the RTX-sulfur packed column as some options for separations.
If you have a more specific question beyond this, I will be glad to follow up with you.
Best regards.
