chromatographic 中文解釋 wordnet sense Collocation Usage Collins Definition
  1. of or relating to chromatography
  2. (chromatography) a process used for separating mixtures by virtue of differences in absorbency
  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) 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 ...
  5. (chromatograph) (KROH-muh-to-grahf): a device that separates substances by pushing them through a material that absorbs each substance at a different rate.
  6. (Chromatography) a laboratory test performed on a pregnant woman's urine to detect illegal drugs, such as cocaine, heroin, and marijuana.
  7. (Chromatography) a procedure used to identify substances, such as drugs of abuse, in urine (The substance is separated or extracted and allowed to move or migrate along a carrier and then identified.)
  8. Chromatography refers to a range of physical methods used to separate and analyse complex mixtures. It involves a separation of components into two phases: stationary and mobile. Biodynamic farmers use this process to test preparation, soil and produce for vitality. ...
  9. (chromatography) The generic name of a group of separation processes that depend on the redistribution of the molecules of a mixture between a gas or liquid phase in contact with one or more bulk phases. The several types of chromatography are: adsorption, column, gas (q.v. ...
  10. (chromatography) 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
  11. (chromatography) 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. ...
  12. (CHROMATOGRAPHY) A generic term for any one of several powerful procedures used to separate one type of molecule from another. ...
  13. (CHROMATOGRAPHY) The separation of chemical substances and particles (originally plant pigments and other highly colored compounds).
  14. (CHROMATOGRAPHY) 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.
  15. (Chromatography) (From Gr. chromo [color] + graphos [writing]) The practice of submitting manuscripts for publication with the original figures drawn in non-reproducing blue ink.
  16. (Chromatography) A practise that allows the separation of a small quantity of soluble compounds.
  17. (Chromatography) 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. (Chromatography) A technique used to separate a sample into its components based on the speed at which they move through a stationary matrix.
  19. (Chromatography) An analytical technique whereby a complex substance is adsorbed on a solid or liquid substrate and progressively eluted by a flow of a substance (the eluant) in which the elements of the substance under investigation are differentially soluble. ...
  20. (Chromatography) 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. ...
  21. (Chromatography) Chemical analysis that separates components into various parts.
  22. (Chromatography) 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). ...
  23. (Chromatography) a technique for separating complex mixtures of chemicals or proteins into their various constituents.
  24. (Chromatography) the separation of a liquid or gaseous mixture by passage over an adsorbent so that each component becomes adsorbed separately
  25. (chromatography) (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.
