Forced-flow planar chromatographic separation can be achieved by application of external pressure (over-

The samples are applied on an outer circular starting line and development proceeds from the periphery of this circle layer to its centre (Figure 13B). This mode of development can be performed with a Camag anticircular U-chamber, shown in Figure 17.

Anticircular chromatography is seldom applied in practice. An example of a chromatogram obtained by this mode of development is given in Figure 18. The spots are compact near the origin and elongated in the direction of the mobile-phase migration.
