I discovered some interesting info on this trace element determination process known as Ashing Procedures, which is covered in chapter 14 of the document entitled "Trace Analysis Guide". Interesting read at the very least, but if you look at the site it comes from - Inorganic Ventures - You'll notice other chapter titles with familiar topics listed under this guide, like:
Introduction to Sample Preparation
Stability of Elements at ppb Concentration Levels
Container Material Properties
and
Acid Digestions of Inorganic Samples
Might be something useful to review.
