| chromatography, high pressure liquid | Liquid chromatographic techniques which feature high inlet pressures, high sensitivity, and high speed. (12 Dec 1998) |
|---|---|
| chromatography, ion exchange | Separation technique in which the stationary phase consists of ion exchange resins. The resins contain loosely held small ions that easily exchange places with other small ions of like charge present in solutions washed over the resins. (12 Dec 1998) |
| chromatography, liquid | Chromatographic techniques in which the mobile phase is a liquid. (12 Dec 1998) |
| chromatography paper | Used in paper chromatography. Synonym: high quality filter paper. Congo red paper, paper impregnated with Congo red; used as a pH indicator, changing from blue-violet at 3.0 to red at 5.0. Filter paper, an unsized paper used in pharmacy and chemistry for filtering solutions; many varieties are used for paper chromatography. (05 Mar 2000) |
| chromatography, thin layer | Chromatography on thin layers of adsorbents rather than in columns. The adsorbent can be alumina, silica gel, silicates, charcoals, or cellulose. (12 Dec 1998) |
| circle absorption anaesthesia | Inhalation anaesthesia in which a circuit with carbon dioxide absorbent is used for complete (closed) or partial (saemiclosed) rebreathing of exhaled gases. (05 Mar 2000) |
| photoelectric absorption | <chemistry, physics> The interaction of an X-ray photon with matter in which the incident photon is completely absorbed, giving up all its energy by displacing an outer shell electron. (05 Mar 2000) |
| molar absorption coefficient | Absorbance (of light) per unit path length (usually the centimeter) and per unit of concentration (moles per liter); a fundamental unit in spectrophotometry. Synonym: absorbancy index, absorptivity, molar absorbancy index, molar absorptivity, molar extinction coefficient. (05 Mar 2000) |
| column chromatography | A form of partition, adsorption, ion exchange, or affinity chromatography in which one phase is liquid (aqueous) flowing down a column packed with the second phase, a solid; the dissolved substances form a partition between the solid and liquid phases depending on the chemical and physical conditions of each phase; the more strongly adsorbed solutes reach the bottom of the column later than the less strongly adsorbed ones. (05 Mar 2000) |
| cutaneous absorption | The absorption of drugs, allergens, and other substances through unbroken skin. Synonym: cutaneous absorption. (05 Mar 2000) |
| high-performance liquid chromatography | <investigation> A lab technique, a type of column chromatography, which uses a combination of several separation techniques to separate substances at higher resolution. Extremely sharp peaks on the elution profile can be produced with high-performance liquid chromatography (HPLC). (09 Oct 1997) |
| high-pressure liquid chromatography | <investigation> A lab technique, a type of column chromatography, which uses a combination of several separation techniques to separate substances at higher resolution. Extremely sharp peaks on the elution profile can be produced with high-performance liquid chromatography (HPLC). (09 Oct 1997) |
| specific absorption coefficient | Absorbance (of light) per unit path length (usually the centimeter) and per unit of mass concentration. Compare: molar absorption coefficient. Synonym: absorbancy index, absorptivity, extinction coefficient, specific extinction. (05 Mar 2000) |
| spectrophotometry, atomic absorption | A highly sensitive technique used to analyze various elements, especially metals, including aluminum, arsenic, beryllium, calcium, copper, iron, lead, and lithium, which are present in trace amounts. The atoms are excited above a ground state by flame vaporization, and the radiation emitted as the molecules return to a ground state is measured in unexcited non-ionised molecules. (12 Dec 1998) |
| disjunctive absorption | Absorption of living tissue in immediate relation with a necrosed part, producing a line of demarcation. (05 Mar 2000) |
