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...
