Dear Zophonias,

	Don't know about specifice techniques or lit. refs., however,
to save funds, why not setup your laboratory as a clearing house for spent
deuterium oxide?  Seems ashame that this expensive material is most often 
discarded after use as NMR solvent.  Simple filtration and distillation
would return it to usable form for your laboratory to use.  
	I imagine that if you offered to pay for shipping, you might very soon
have all the D2O that you will ever need. 

Good luck, 
Best regards,

Lawrence Byrnes,  NMR spectroscopist,
