DictionarySeechromatographyhigh-performance liquid chromatography
high-performance liquid chromatography[¦hī pər′fȯrm·əns ‚lik·wəd ‚krō·mə′täg·rə·fē] (analytical chemistry) A type of column chromatography in which the solvent is conveyed through the column under pressure. Abbreviated HPLC. high-performance liquid chromatography
high-per·for·mance liq·uid chro·ma·tog·ra·phy (HPLC), a chromatographic technology used to separate and quantitate mixtures of substances in solution. A sample is injected into a moving stream of solvent that flows through a column and detector. Separation during passage through the column occurs by absorption, partition, ion exchange, or size exclusion. The technique is commonly used in laboratories to measure organic compounds including steroid hormones, pesticides and poisons, toxic and carcinogenic compounds, and drugs. Synonym(s): high-pressure liquid chromatographyhigh-per·for·mance liq·uid chro·ma·tog·ra·phy (HPLC) (hī pĕr-fōr'măns lik'wid krō'mă-tog'ră-fē) A chromatographic technology used to separate and quantitate mixtures of substances in solution. The technique is used to measure organic compounds, including steroid hormones, pesticides and poisons, toxic and carcinogenic compounds, and drugs.
Synonym(s): high-pressure liquid chromatography. high-performance liquid chromatography Abbreviation: HPLC
Application of high pressure to liquid chromatography technique to increase separation speed and enhance resolution. Synonym: high pressure liquid chromatographySee also: chromatography |
