Problem- Considering TLC and semi-microscale column chromatography techniques: how are they similar and how are they different? Make sure you explain how they are different in terms of polarity (bottom of TLC plate but top of column). What is the role of the solvent(s) (mobile phase) in TLC? In column chromatography?
