Measurement of H2S in natural thermal waters.

[Procyon]

I'm trying to implement a H2S (hydrogen sulfide) measurement for thermal
water in an in situ sample collection by an environmental microbiology
and microbial ecology laboratory. I need to stabilize the H2S in the
water sample to measure the H2S levels later.



Due to the higly volatility of H2S, I'm evaluating (and understand the
theory of) the methods of blue methylene or diamine; but I don't know
the practical limitations for an in situ sampling neither what is the
proper container for water with volatile H2S.

One thing that will help. The proper container is one that's full to the brim so there's no air space to lose H2S to.
