Chromatography is an analytical technique for the separation of molecular mixtures by distribution between two or more phases. There are many types of chromatography, including high-performance liquid chromatography (HPLC), gas chromatography (GC), ion-exchange chromatography (IEC), and gel-permeation chromatography (GPC).
