Dominik,
Boron nitride has been used as a diluent.
You might check Polymer Source (www.polymersource.com) for the polyethylene
you're looking for, however they seem to be quite expensive. ChemPlex (
www.chemplex.com) also has binders and specializes in products for XRF
analysis.
HTH,

Dear list,
for many years, I have used "Merck Uvasol Polyethylene for spectroscopy" PE powder as a diluent and binder for pressing self-supporting pellets especially of air-sensitive substances. When I today wanted to order a new bottle, I had to learn that it's not available anymore (actually, since 2002... :-)).
Does anyone of you know about any other supplier of spectroscopy-grade polyethylene powder? And more general, which binder/diluent do you use for preparing pellets of sensitive substances ?
Best regards, Dominik
