I would like to post this question on your newsgroup.


My name is Jaime Demick and I am an intern at NASA Goddard Space Flight
Center in the NASA Academy program.  I am researching techniques in
chemical conversion and physical separation of gases for use in a mass
spectrometer.  Specifically, I am interested in separating CO2, CO, and
N2 from each other, and from a gas mixture that may include the
following species:

O3, CO2, H2O, N2, 40Ar, O2, CO, 36Ar, 38Ar, Ne, Kr, Xe, N2O, NO2, OCS,
HCl, HCOH, H2S, PH3, SO2, NH3, CH4, C2H6, C2H4, and C2H2

for the purpose of obtaining more accurate isotopic ratios.

I need to find out what research has been and is currently being
conducted in these areas to avoid redundancy in our experimentation.
Any input regarding chemical conversion techniques used for separation
of these species and there constituent isotopes, and information
regarding physical separation of these species would be greatly
appreciated.
