|---|---|
| chromatograph | To perform chromatography. (05 Mar 2000) |
| chromatographic | Pertaining to chromatography. (05 Mar 2000) |
| chromatography | <investigation> Techniques for separating molecules based on differential absorption and elution. Term for separation methods involving flow of a fluid carrier over a nonmobile absorbing phase. (18 Nov 1997) |
| 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, affinity | A chromatographic technique that utilises the ability of biological molecules to bind to certain ligands specifically and reversibly. It is used in protein biochemistry. (12 Dec 1998) |
| chromatography, agarose | A method of gel filtration chromatography using agarose, the non-ionic component of agar, for the separation of compounds with molecular weights up to several million. (12 Dec 1998) |
| chromatography, deae-cellulose | A type of ion exchange chromatography using diethylaminoethyl cellulose (deae-cellulose) as a positively charged resin. (12 Dec 1998) |
| chromatography, gas | Fractionation of a vaporised sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix. (12 Dec 1998) |
| chromatography, gel | Chromatography on non-ionic gels without regard to the mechanism of solute discrimination. (12 Dec 1998) |
| 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, 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) |
| chromatoid | A refractile substance composed of chromatin, thought to be a non-glycogen food reserve contained within the cytoplasm of certain protozoa; seen in cysts of Entamoeba histolytica as rounded bars or chromatoidal bodies in contrast to the splintery form of chromatoid bodies in cysts of Entamoeba coli. Origin: chromato-+ G. Eidos, form (05 Mar 2000) |
