chromatography[krō′mə täg′rə fē]
- The definition of chromatography is a process of separating out different parts of chemical mixtures onto an absorbent material that can then be individually analyzed because different parts are caught on the material at different rates.
An example of chromatography is when a chemical reaction is used to cause each of the different size molecules in a liquid compound to separate into their own parts on a piece of paper.
Origin of chromatographychromato- + -graphy
(countable and uncountable, plural chromatographies)
- (chemistry) 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.
