Chromatography

Any of a diverse group of techniques used to separate mixtures into their constituents through differential migration and absorption by a solid such as a column of silica (column chromatography) or a strip of filter paper (paper chromatography). One common use in human biology is the isolation of peptide fragments along a filter paper after digestion by a proteolytic enzyme (such as trypsin) of the original protein.
