Hi,
        Can anyone provide me with basic methodology for running dD of
water using a MultiPrep (either Micromass or Matt Emmons version).  We
routinely run d18O of water but have yet to try dD.

Do you use Pt-Al catalyst? Hokka beads? Glass rods?
Do you use the auto hydrogen injection?  A glove bag?
What temperature for multiprep?  Equilibration times?

Thanks in advance for any info.  Jason
