Modern XRF's for Elemental Analysis (oils)?

andrewMember

Dear all,

Don't know if any of you have had a look at the latest XRF's coming out of Japan and the US. Small, simple, autosampler trays, and coming in significantly cheaper than ICP's or RDE's.

We ran a couple of tests on a demo model we had access to and the results seemed pretty good.

-Using Helium (or alternate).
-Plastic cups with mylar sheaths used.
-Internal components are now protected from oil spills.

My query is:
-Can you list significant disadvantages of the XRF for oil analysis?
-Difficulty with certain elemental wavelengths? -Settling of heavier particles to the bottom of the sample cup (=higher results)?

Any helpful comments would be appreciated.

Regards

Andrew
