Yes, I have ways could monitor temperatures practically anywhere in the system. Monitoring temperature in the Hexane slurry itself is definitely on my list. But I am a little unclear as to the nature of your speculations? When you say 'hydrated, do you mean 'hydrogenated', or 'hydrated' as in wet? (The opposite of 'dehydrated' - English is a bitch sometimes! ) And in either case, what are you speculating I might see?
