Bonded-phase chromatography
A stationary phase chemically bonded to a support that is used for the separation. It is the most commonly used LC mode. The most popular support used is microparticulate silica gel. An organosilane, such as octadecyl (for reversed-phase chromatography), is the most accepted type of bonded phase. Approximately 70 percent of all HPLC is carried out on chemically bonded phases.
