The separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates,
  1. The separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates

  1. a process used for separating mixtures by virtue of differences in absorbency
  2. (chromatographical) chromatographic: of or relating to chromatography
  3. 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. ...
  4. Chromatography is a 2004 Post Trip Hop album by Second Person.
  5. 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 ...
  6. a laboratory test performed on a pregnant woman's urine to detect illegal drugs, such as cocaine, heroin, and marijuana.
  7. This is when you use a system containing a mobile phase (usually a liquid in general chemistry classes) and a stationary phase (something dissolved in the liquid) to separate different compounds. ...
  8. In chemistry, analytical technique used for the chemical separation of mixtures and substances. The technique depends on the differential distributon of solute between the mobile and stationary phases.
  9. a process in which a chemical mixture carried by a liquid or gas is separated into components as of result of a distribution of the dissolved substances
  10. Chemical analysis that separates components into various parts.
  11. The separation of chemical substances and particles (originally plant pigments and other highly colored compounds).
  12. a separation technique which uses the differential rates of diffusion of different sizes of molecules in gas (GC), liquid (HPLC), on paper, and in thin layers of silicate on glass, aluminum or plastic plates (TLC). Now much used in lichenology.
  13. A series of related techniques for the separation of a mixture of compounds by their distribution between two phases. In gas-liquid chromatography the distribution is between a gaseous and a liquid phase. In column chromatography the distribution is between a liquid and a solid phase.
  14. A technique used to separate a sample into its components based on the speed at which they move through a stationary matrix.
  15. (Gr. chroma, colour + graphein, meaning to draw or write) 1. A method for separating and identifying the components of mixtures of molecules having similar chemical and physical properties.
  16. Any of a variety of techniques used to separate mixtures of drugs and their metabolites and other chemicals into individual components based on differences in their relative affinities for two different media: a mobile phase and a stationary phase. ...
  17. A procedure for separating chemically similar molecules. Segregation is usually carried out on paper or in glass or metal columns with the help of different solvents. ...
  18. A process which separates and/or analyses gases or dissolved chemical materials.
  19. A way of separating substances based on their characteristics usually using a liquid mobile phase and a solid stationary phase.
  20. (From Gr. chromo [color] + graphos [writing]) The practice of submitting manuscripts for publication with the original figures drawn in non-reproducing blue ink.
  21. Literally means coloured writing, it is a technique used to separate coloured materials. You can use chromatography to separate the colours of ink (maybe black ink contains red, blue and brown dyes) or food colourings (smarties are good for this). ...
  22. a technique for separating complex mixtures of chemicals or proteins into their various constituents.
  23. the separation of a liquid or gaseous mixture by passage over an adsorbent so that each component becomes adsorbed separately
  24. A practise that allows the separation of a small quantity of soluble compounds.
  25. Chromatography refers to a collection of analytical techniques used to separate and analyze complex mixtures by employing a system with mobile and stationary phases.
