Term
|
Definition
| In chromatography, this parameter is the time needed for mobile phase to travel the length of the column. |
|
|
Term
| Adsorption Chromatography |
|
Definition
| A technique in which solute equilibrates between the mobile phase and adsorption sites on the stationary phase. |
|
|
Term
|
Definition
| A technique in which a particular solute is retained by a column by virtue of a specific interaction with a molecule covalently bound to the stationary phase. |
|
|
Term
|
Definition
| A graph showing chromatography detector response as a function of elution time or volume. |
|
|
Term
|
Definition
Net transport of a solute from a region of high concentration to a region of low concentration caused by the random movement of molecules in a liquid or gas (or, very slowly, in a solid). |
|
|
Term
|
Definition
| Defined by Fick's first law of diffusion: J = -D(dc/dx), where J is the rate at which molecules diffuse across a plane of unit area and dc/dx is the concentration gradient in the direction of diffusion. |
|
|
Term
|
Definition
For a solute partitioned between two phases, the total concentration of all forms of solute in phase 2 divided by the total concentration in phase 1.

Term
|
Definition
| What comes out of a chromatography column. Also called effluent. |
|
|
Term
|
Definition
| Solvent applied to the beginning of a chromatography column. |
|
|
Term
|
Definition
| Process of passing a liquid or a gas through a chromatography column. |
|
|
Term
|
Definition
| Process in which a solute is transferred from one phase to another. |
|
|
Term
| Ion-Exchange Chromatography |
|
Definition
| A technique in which electrolytes are separated from nonelectrolytes by an ion-exchange resin. |
|
|
Term
|
Definition
| In chromatography, the distance per unit time traveled by the mobile phase. |
|
|
Term
|
Definition
| Diffusion of solute molecules parallel to the direction of travel through a chromatography column. |
|
|
Term
|
Definition
| Two liquids that form a single phase when mixed in any ratio. |
|
|
Term
|
Definition
| In chromatography, the phase that travels through the column. |
