Elf: Sorry to have brought on that exasperated sigh, but thanks for spelling it out. SWIP will report back on his findings.
He should have been familiar with the terminology, but with no tests in this class it's easy to allow memory of such data to slide away.
Os: SWIP has been harping on chromatography, he thinks, longer than you have. He has even made a few sad, abortive attempts. The more he learns the more complicated it all sounds, however. Suppose, for example, we found just the right mix of materials to seperate out polysorb. Everyone would start using it until they stick something new in the mix. Then it would all start again.
That's what we do now, but column chromatography looks like a fairly painstaking, complicated process. If it could really be done effectively with something like diatomaceous earth as a substrate, a florescent tube, and an eluent that wasn't any more exotic than what's found at the hardware store it would be great. Any suggestions along those lines will be gratefully accepted.
None of the research he did on polysorb 80 spoke at any length on CC, but SWIPs impression is that it is one of the more difficult substances to deal with. He might be wrong, but for now it didn't look like it was going to be an expedient means.
