In the conventional mode of development in planar chromatography the mobile phase is supplied to the chromatographic plate by direct contact with the adsorbent layer and the flow rate of the eluent is controlled by capillary forces.

The main modes of chromatogram development are linear, circular and anticircular. The most popular mode is linear development owing to its simplicity; no sophisticated equipment is used to apply the eluent to the chromatographic plate, as it is in circular and anticircular modes. In practice, linear development provides the resolution and reproducibility required for most qualitative and quantitative determinations. All three modes can be extended by applying continuous or multiple development.
