The term TLE will be used to refer to all techniques carried out within chromatographically active thin layers and with electric fields being employed to influence the separation. This will encompass a number of different modes of separation, including those that are dominated by electrophoretic analyte migration but which, due to the nature of the layer, include some element of chromatographic retention. Conventional gel-based electrophoresis is therefore distinguished from TLE by the electrophoresis in TLE being carried out in a chromatographically active layer of material such as silica, alumina or cellulose. TLE therefore excludes gel electrophoresis carried out in cast gel slabs of materials such as polyacrylam-ide that are commonly used for the separation of proteins and DNA. Paper electrophoresis is now largely obsolete and is not therefore covered.
