esteemed collective wisdom,

using equilibrium technique (I have a MultiFlow), I wonder if it would be
possible to determine D and 18O on the very same sample in two consecutive
runs.

Idea is loading around 200 microliters of sample + Hokko beads into the
Labco vials and equilibrate with H2 mixture, after measurement leaving the
samples (and catalyst)  in the tray so they don't have to be opened,
readjust tray temperature, swap gas mixture to CO2 and run the oxygen
measurement.

I can't really think a reason why it shouldn't work, but I may miss
something.I tested the septa and they seem to hold for various punctures...

cheers
Chris
