www.ocf.berkeley.eduRP-HPLC, or Reverse-Phase High-Performance Liquid Chromatography is a type of chro-matography the features a liquid mobile phase, higher resolving power than traditional liquid chromatography, and a speci c combination of stationary- and mobile-phases that results in separations that are the opposite of a \traditional" HPLC.

Separation techniques: Chromatography
jag.journalagent.comphase is liquid it is termed as liquid chromatogra-phy (LC), and if it is gas then it is called gas chro-matography (GC). Gas chromatography is applied for gases, and mixtures of volatile liquids, and solid material. Liquid chromatography is used especially for thermal unstable, and non-volatile samples [5].

Principles of Gel Filtration Chromatography
www.edvotek.comGel fi ltration chromatography (sometimes referred to as molecular sieve chromatogra-phy) is a method that separates molecules according to their size and shape. The sepa-ration of the components in the sample mixture, with some exceptions, correlates with their molecular weights. In these cases, gel fi ltration can be used as an analytical ...
