moisture versus oxygen ?



Dear friends,

here is one thought which might help in the solution of our
humidity versus oxygen interpretation problem.
It is rather vague, please feel free to dispose it
right away, if there is an argument I am not aware of.


Our TPC-hydrogen vessel has cathodes and anodes on high
voltages, which is the typical model of a highly sophisticated
electrolysis cell (sorry Malte).
So an H2O molecule which gets close to the anodes will dissociate
leaving a free oxygen atom (or an O-H molecule).
Now at room temperature oxygen atoms need a catalyzer to recombine
with hydrogen, meaning  the recombination is at least very slow,
even in a pure hydrogen atmosphere.

Our Pura moisture detector / dew point transmitter
is only sensitive to moisture and not to dissociated oxygen.

Hence, we see more oxygen events in the impurity finder
than expected from the moisture measurement.


Can we test this hypothesis by running (after the data run)
with the high voltages on and off and check if there is
a change in the humidity reading ?


	    Thanks for your comments
