A new Chloride-Selective Carrier and its Evaluation in Ion-Selective Electrodes

 A new chloride selective carrier, the tributyltin cinnamate, is evaluated for its analytical characteristics when incorporated in liquid polymeric membranes of ion-selective electrodes. The electrode constructed based on this carrier exhibited an improved selectivity towards chloride as compared to those based on the existing chloride carriers, completely satisfying the selectivity for direct blood measurements. Additionally, the response time of the sensor is fast, while the good signal stability allows for the application as a stand-alone device or as a detector in FIA system. The electrode exhibited analytical characteristics suitable for its employment in a variety of real-sample analysis.
