Adsorption chromatography
One of the basic LC modes. Relies on the adsorption process to effect the separation. Silica gel and alumnae are the most frequently used supports; molecules are retained by the interaction of their polar functional groups with the surface functional groups (e.g., silanols of silica). | ||||

Chromatography
Chromatography (from Greek χρώμα:chroma, colour and γραφειν:"grafein" to write) is the collective term for a family of laboratory techniques for the separation of mixtures. It involves passing a mixture dissolved in a "mobile phase" through a stationary phase, which separates the analyte to be measured from other molecules in the mixture and allows it to be isolated.
