Hi Jools,
In the past we've obtained alumina for use as an internal standard from this
company:

You can check your material against an NIST standard bef

Julian,
First, the best idea would be to use a NIST standard
Hi all,
I've been asked to do some quantification on some samples which are
predominantly silica, which means a reasonable amorphous component is pretty
much inevitable. I'm thus looking for a suitable internal standard for spiking,
but as this could be quite a big project moving forwards i don
rutile to use as internal standards except
NIST? The SRM standards are very expensive for very little
quantity.

Does anyone have a suggestion for a vendor that has crystalline
corundum, zincite and/or rutile to use as internal standards except
NIST? The SRM standards are very expensive for very little quantity.
