Dear all:
We need containers for sampling and storage of CO2 gas for isotopic measurement.
It will take a couple of days to bring the gas samplers from our site and
undertake the isotopic measurement.
Does anyone have comments about the materials of the gas samplers, and about
the procedure for gas sampling?
Previously, topic on materials of stopcocks is discussed on this mailing
list.  Then we would like to know if this effect
is detectable in carbon isotopic measurements of CO2 gas (several hundred
ppm) stored for a week.
Any comments are welcomed.

Thanks in advance.
Keisuke
