yea i have no idea what im doing either but since i have to be in the chem lab 2morrow to help out with an organic class i might as well entertain myself a little while im there. I was thinking about diluting the concentration a little, bring the temp down a hell of a lot then play around with the centrifuge a lil bit to see if i can get it to precipitate at all, i know that if it warms up at all it will resuspend. Hmmm since the BA suspends it if can get the BA out of the solution it will reduce the solubility of the test..... hmmm if anyone has any ideas please share
