Rotation planar chromatography development mode

The main difference between the first four methods [normal chamber RPC (N-RPC), microchamber RPC (M-RPC), ultra-microchamber RPC (U-RPC), and column RPC (C-RPC) 1 lies in the size of the vapor space, that is an essential criterion in rotation planar chromatography. The circular mode of development is always used for on-line preparative separations by all of these methods. The sample is applied near the center of the layer, and the mobile phase is forced through the stationary phase from the center to the outside of the round plate/planar column. The separated compounds are eluted from the layer/planar column as a result of the centrifugal force and collected in a fraction collector.
