liquid chromatography on a reversed-phase support
1Reversed-phase chromatography — (RPC) includes any chromatographic method that uses a non polar stationary phase. The name reversed phase has a historical background. In the 1970s most liquid chromatography was done on non modified silica or alumina with a hydrophilic surface… …
