Hello everyone,
Our lab has been asked to analyze the hydrogen/deuterium ratio
of a water sample from a crater lake. We have tried 3 times
(zinc reduction method) but the results differ from each other by at
least 10 per mil. The problem is that the water is very acidic
(pH 1 or 2) and we can't raise the pH without adding an external
source of hydrogen (hydroxide). Does anyone have an idea as to
how we could obtain the hydrogen/deuterium ratio of this sample?
Thanks very much
Natalie Morisset
