air monitoring w/bubblers

[glenn_sturchio@merck.com (Glenn Sturchio)]

Greetings:

We have installed EG&G EL 700 air monitoring systems.  The basic idea is 
that tritium oxides and compounds travel through an initial set of bubblers, 
a furnace (w/catalyst), and a second set of bubblers.  The bubblers are full 
of ethylene glycol and trap 99.9% of the oxide.  The furnace converts 
everything to oxide.  Therefore, the first set o' bubblers integrates the 
oxide and the second set integrates the not-oxide.  Fairly straightforward 
for tritium.

Our question:  Does anyone have experience (or hints) on using bubblers for 
C-14 compounds other than CO2?  We're currently using ethanolamine.  How 
about S-35?

We intend to run some bench top experiments, but any additional guidance 
would be appreciated.

Thank you,
Glenn Sturchio
