It introduces key concepts like chromatographic resolution, retention time, selectivity, and column efficiency. The content explains how solutes are separated and how to analyze chromatographic data to assess separation quality.

Instead of applying a sample on a thin layer of silica or alumina, a sample is deposited on a cylinder of adsorbent and solvent is continually applied with pressure until the components completely drain from the cylinder. With this modification, components can be not only separated but collected into different containers, allowing for purification of mixtures.

In this section we develop a general theory that we may apply to any form of column chromatography.

It is very flexible because several different compounds can be separated from each other in one experiment. Practically speaking, TLC is often used only as an analytical tool rather than as a method of purification. It is used to quickly determine if a mixture is pure, how many compounds it may contain, and what combination of eluent and stationary phase can be used to separate the compounds.
