Modes of Paper Chromatography

In most of its practical aspects (e.g. sample application, equipment such as developing tanks and visualization procedures), paper chromatography somewhat resembles TLC. The most noticeable difference is that, as the paper is not rigid, it must either be suspended from an appropriate support during development or arranged in such a way as to be self-supporting. Only the major types of paper chromatography are described below, but it should be noted that there were many minor variants of the technique (e.g. centrifugal, continuous).

Figure 2 (A) One method of ascending chromatography involved the formation of a self-supporting cylinder, held together with tongued clips. The cylinder was then placed in a tank containing the solvent for development (B).
