Potassium ionselective microelectrodes with a tip diameter of 10 pm are described. The ionophore used is 2,2'-bie[3,4-(16-mow-6)-2-nitrophenylc~b~ox~ethyl]~~decane in a conventional mixture with sodium tetraphenylborate, an ether and PVC. The electrode provides Nernstian response over the range 1O-5
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-
