Some results obtained at the above department in the field of contactless conductivity detection (CCD) are reviewed, in the framework of the state‐of‐the‐art of the field. Several detection cells have been designed and tested. It has been shown that the performance of systems with planar and semitubular electrodes is fully comparable with that of common cells with tubular electrodes and that these systems have advantages in simpler construction and a greater operational versatility. Important characteristic parameters are discussed, primarily the electrode effective length, the gap between the electrodes and the thickness of the dielectric layer. Possibilities of using thin insulated wire electrodes for CCD detection in flow injection analysis are demonstrated.
