Great information on testing for trace elements. Obvious to me we have some heavy hitters at bat here
I have some knowledge of Neutron Activation Analysis testing from my Georgia Tech days. I wonder if anyone has tried or has any knowledge of it?
For anyone interested, this is a Link to some information about it, I found it using Google search. one side effect is that the item is now radioactive and depending on the isotope half life it may be a while before it decays down.
