Title: Complete Online TLC Guide
Post by: Altered State on December 25, 2019, 10:57:45 PM

Apologies beforehand if this is the wrong sub-board.

I recently managed to put together a big online resource that might be useful for both students and teachers.
It is a more or less comprehensive guide for thin layer chromatography. I really like the result and I hope it can be useful for any of you:

Feel free to check it out, use any of the materials, or share it wherever you like.
Also, feedback is highly welcome!

Its great :)

Also what worked for me: instead of using triethylamine as a part of my mobile phase, I made (i think) 5% TEA in hexanes and dipped the TLC plate into it and let it dry before spotting the mixtures. It doest work for collumns but I sometimes got some 2nd solvent front while using TEA as a part of my mobile phase
