I would like to hear what PE knows about analysis of competitors materials.

I certainly see how it would be easier, and cheaper.
The changes upon drying affect- I belive- mainly pH, pAg (and naturally water content)... things strongly affected by final additions...so if you compared both types of analyses; one might learn more than either alone.

Quite a bit could be learnt either way, if the potential ROI were great enough....but generally, I don't think analysis is of that much use unless you have a specfic problem or goal in mind.

I wonder what Kodak has learned that way?

The less I forget the more I will know!
