Chromatography is a technique used in analytical chemistry to separate and identify components of mixtures. The name comes from the Greek term for "color writing" because this method was originally used to separate colored samples. Today a variety of...

The term chromatography was originally used about 100 years ago by a Russian botanist, Mikhail S. Twsett (1872-1919) to describe the separation of bands of plant pigments (chlorophylls) extracted from green leaves. The process used with petroleum ether...

Chromatography is the process of separating mixtures of chemicals into individual components as a means of identification or purification. It derives from the Greek words chroma, meaning color, and graphy, meaning writing. The word was coined in 1906...

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...

Column chromatography: separation method in which different components of a mixture migrate down through a column at different rates of speed based on their various chemical properties Virtually all protein purification processes rely on at least one column chromatography step, The number and...

Column chroniatography: Separation method in which different components of a mixture migrate down through a column at different rates of speed based on their various chemical properties. Chromatography can be described simply as a separation method in which different components of a mixture...
