Ha sorry, I may know my chemistry but I did not know charts such as that existed. Could you link me to it? In a real lab there are way better ways of analytical testing to know what compound is which, but for simple extraction purposes for the average self-chemist, I suppose that guideline could work.

Personally since I have done literally hundreds of columns, I would still be skeptical about what I have obtained because I have been stumped many times (such as spots overlapping rf value) even with other tools such as Mass spec and NMR. My skepticism would be furthered by the fact that crude extraction mixtures still often contain MANY other organics. It can still be done though and once a TeK is established then you should be good to go (I have a feeling someone already developed a procedure for this but since I am new to the scene I have not come across it yet).

I am interested to see more info on this since I do not yet have any DMT specific experience with columns.
