Hi Carl,

Spot on!

Question: How much material is required for the oxygen isotope testing???


When we were working on the H-Metal, the ICPMS-LA (Herd) tests completed
on the last one used less than 100 milli-grams.
And previous INAA (Actlabs) testing used 100 milli-grams. And, as you
know sample size was nill!
  In either case, is not like you have to cut a third of it off. Not
sure about the OI tests.

Jim
