✦ Synopsis

The use of potentiometric microelectrodes as detectors for anions in capillary electrophoresis is demonstrated.

The detector electrode with a tip diameter of 3 pm is inserted into the end of a fused silica separation capillary with an internal diameter of 25 Frn. The separation and detection of Cl-, NO;, NO;, Br-, I-and CIO; down to concentrations of 10 pg kg-' is reported.
