| batch culture | A closed system culture of microorganisms with specific nutrient types, temperature, pressure, aeration, and other environmental conditions, where only a few generations are allowed to grow before all nutrients are used up. Compare: continuous culture. (09 Oct 1997) |

| batch processing | <technique> Growth in a closed system with a specific amount of nutrient medium. In bioprocessing, defined amounts of nutrient material and living matter are placed in a bioreactor and removed when the process is completed. (14 Nov 1997) |
| gradient elution | Elution in column chromatography in which a changing pH or ionic strength is used to separate substances. (05 Mar 2000) |
| elution | 1. The separation, by washing, of one solid from another. 2. The removal, by means of a suitable solvent, of one material from another that is insoluble in that solvent, as in column chromatography. 3. The removal of antibodies absorbed onto the erythrocyte surface. Synonym: elutriation. Origin: L. E-luo, pp. Lutus, to wash out (05 Mar 2000) |
| elution profile | <chemistry> A graph made to show how much material is being carried out of the column by the eluant in column chromatography over time. The graph will show a number of different peaks, each peak represents a different separated material from the original mixed substance. (09 Oct 1997) |
| elution volume | <chemistry> The amount of eluant which has passed through the column in column chromatography before a particular peak in an elution profile appears, or before a specific substance of interest comes out with the eluant, separated out of the original mixed substance. (09 Oct 1997) |
