Dear Istvan and others,

There is a recent publication on this matter:
Huber Ch., Leuenberger, M. and Zumbrunnen, O. (2003) Continuous extraction
of trapped air from bubble ice or water for on-line determination of isotope
ratios. Anal. Chem., 75: 2324-2332.
Might be of interest for you.

Best wishes,
Pier de Groot.
