Thin-Layer Chromatography

[Vininim]

Has anybody done any TLC on net for analysis? We could even make an atlas for (ballpark) comparision.

The difficulty here is that for home lab environment, and safety, we would be doing static organic with moving polar process. Organic layer, in a kitchen environment, could be too inconsistent or expensive.

But anyway, I'm surprised no one tried it when I did a search. Would it be too low performance to not have any use at all? I would assume that as blobish as it would be, it could give some insight about extraction methods and their profiles. We could cross reference with "subjective experience" from vaping.

wow .... even with my education in mech engineering Im lost as to what you are expressing.... if you could express your ideas in a less formal manner we may be able to converse with you....

Here is a video demonstrating the technique: https://www.youtube.com/watch?v=w0FyQ_tO15U

The visualization step there can be tonned down to UV lamp + marking.

The problems I describe have to do with organic solvents, specially apolar ones, usually being hazardarous to handle, so there is a need of doing reverse tlc with some apolar organic coating in the plates and use of more polar solvents like water, alcohol, PG, etc. I've never seen it being done with mineral oil (not sure how fast it moves throught the plate , and then you need to get hide of it or things will just dissolve heh).

The problem I can think of would it'd be hard to find a standard to judge against, so you wouldn't know which spots are what. I think a column chromatography setup would work better since you could distill off the resulting solution and check boiling points for reference.

Maybe run some columns, figure out what you have, run some TLC plates with that and take notes, then we'd have a standard to start with.
