Paper Abstract

A novel type of a miniature transducer with back-side contacts for potentiometric sensors is described in this paper. A back-side contact type transducer is especially suitable for the design of flow chemical sensors. The sensor structure is compatible with a flow-head used for multiparameter measurements. Unmodified transducers can be used as chloride sensors. Moreover if the chip is covered with ion-selective membrane it is possible to construct a sensor for given ion. Measurement properties of the designed transducers were determined in the experiments with chloride ions as well as interfering ions. Two types of the sensors were constructed: for flow or batch measurements. A reference electrode was integrated with the sensor in the latter version.
