RE: Deuterium Oxide 100%

[Simon "M." Jerome <smj1@npl.co.uk>]

The answer is maybe (!) since the enrichment process probably enriches 
the heavier isotopes. Having said that, measurements on >99.9% 
Deuterium Oxide that I've done have not revealed any measurable tritium 
content. The best thing to do would be to measure it by liquid 
scintillation counting first and then decide....
