Hi, I was wondering if someone out there would like to discuss
various ways of dissolving pottery and geologic standards for ICP-MS.
Off-line or on-line is fine.

Most of the papers I've gotten a hold of just say HF-HNO3 solutions
(or HClO4-HF), and don't go into detail.  Either that or if someone could
provide a good solid, detailed reference that would be handy (here in Japan
my library access to browse is limited and it helps to have specific
references when going to the Diet library....).

I'm trying to measure the REEs
 and some of the transition metals.  I'm using Geol. Survey of
Japan standards JG2 and JB3 to monitor precision and accuracy.  From the
values I'm getting, its clear I've got a problem in either the disolution
or somewhere else....

Sorry to start Tuesday off with such a dumb question,

(PS--I'm normally an XRF or microprobe user, but for some dumb reason,
I decided ICP-MS for this current project.....)
