CHEM 344 Thin Layer Chromatography
6. Using tweezers, dip the TLC plate into the solution of PAA stain in a fume hood. The plate should be dipped smoothly in one motion – your TA will demonstrate. 7. Wipe excess stain from the back of the plate (glass part) and place it on a hot plate for ~20 sec. Allow the solvent to evaporate and look at the spots. 8.
