Rajesh,

Try silver wool heated to several hundred degrees C. It worked fine for an
off-line prep system here.

Dear all

Could anyone suggest a suitable chemical for trapping H2S (which might be
present in anoxic sea /lake waters) but not affecting trace gases like CO
and H2 (as these are species to be measured from anoxic waters) .

Thanks
Rajesh
