This type, in which the mobile phase is a liquid, is the oldest known form of chromatography, with the earliest applications involving preparative methods of separation (for which it is still used today). Depending on the nature of the stationary phase (nature of interactions determining the separation of solutes), we can distinguish between liquid/solid chromatography (LSC), liquid/liquid chromatography (LLC), ion chromatography (IC), and size exclusion chromatography (SEC) (also known as gel permeation or gel filtration chromatography depending on the nature of the stationary phase).
