Vegetable oil thet has been hydrogenated or oxidized will have a different spectrogaphic profile than "virgin" -- as you put it -- vegetable oil. This isn't rocket science here, folks. Well, on second thought, maybe it is. At any rate, I cut my teeth, so to speak, on IR spectroscopy of Green River Oil Shale while getting my MSChE. I've been using IR throughout my career and love it as an analytical tool. Perhaps some component separation would be necessary, first. If so, TLC (no, not "tender, loving, care," but Thin Layer Chromatography) probably would be the means of choice. Anyhow, don't look a gift horse in the mouth, Bob! I'm going to analyze the stuff for J.D. gratis, for zero, ziltch. (Hey, if it helps eliminate fossil fuel powered vehicles, I'm in favor of it.) -- Jay [Non-text portions of this message have been removed] ------------------------ Yahoo!
