<p>A method and apparatus for increasing detector sensitivity in a Capillary Zone Electrophoresis detector is disclosed. A narrow bore capillary (10) includes an injection end (12) and an output end (30). Each end is placed in a reservoir (14,28) containing a buffer solution (15) and a sample of solute (16). The solute (16) comprises at least one unknown constituent component (17). An electric field is imposed across the buffer solution (5) and solute (16) in the capillary (10) by a power supply (22) coupled to leads (20,24) and electrodes (18,26). A source of ultraviolet light (38) illuminates a cell (32) within the capillary (10) and a sensor (42) measures the absorbance of radiation by the solute (16) to detect the constituent components(17).</p> |
