8.5 TLC is commonly employed with column chromatography to monitor the separation of colorless compounds. The column is allowed to elute into many containers, usually test tubes. This is followed by a TLC on a long plate containing the same stationary phase as the column chromatography. Since a large number of tubes must be spotted, by spotting only every other (or every three etc.) tube on the plate. After visualization (by UV), the TLC plate is used to judge which...
