I considered GC with a flame ionization detector.  In looking at the 
method though, it uses hydrogen as a carrier gas.  Could you use helium as 
a carrier gas and still get the same results?  And did you use the columns 
that Agilent lists or did you use a different column resin?

And the follow up question - do you know of independent test labs which 
could do the GC testing that you describe?

Once upon a time I worked on H2 darkening of optical fibers, and I 
analyzed
H2 with gas chromatograph.

Good morning all,

I am posting this question for a colleague (not Hillman).

Take a look at this picture which Steve has graciously posted on his web
page.

http://stevezeva.homestead.com/Bowed_Electrolytic.jpg

This is an electrolytic capacitor and I don't have any access to the
processing history.  Presumably it went through reflow.  My colleague
would like to determine if there is hydrogen in this swelled device and if
so, what percentage.  There is presumably both liquid and gas inside the
swelled area which would complicate any standard residual gas analysis.
Hydrogen is too light for GCMS detection.

OK all you chemists, how would hydrogen presence and concentration be
determined here? And do you know of any commercial labs which would
perform that service?
