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.

(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.
