Substantiv
chromatography - Any of various techniques for the qualitative or quantitative separation of the components of mixtures of compounds; all characterised by the use of a mobile phase gas or liquid moving relative to a stationary phase liquid or solid - the differences between the rates of migration of the compounds between the two phases effects the separation.

Chromatography (from Greek χρῶμα chroma "color" and γράφειν graphein "to write") is the collective term for a set 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 based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus changing the separation.

chromatography
A method of separating and analyzing mixtures of chemical substances by selective adsorption in a column of powder or on a strip of paper.
