Abstract

This article reviews the use of a wall-jet type flow-through detector for the potentiometric determination of quinine and paraquat ions, respectively, undertaken within our research laboratories. The detector allows the evaluation of the analytical response characteristics of the poly(vinyl chloride)-based membranes to be done in the flow injection analysis mode. Such ion-selective electrode membranes, containing either ion-exchangers or neutral carrier type of electroactive component, in conjunction with appropriate plasticizing solvent, and sometimes other membrane additive as was the case for paraquat selective membranes, can be conveniently applied to the detector assembly. Utilization of the flow-through detector allows studies on the sensing of the antimalarial drug, quinine, and the herbicide, paraquat, to be conducted conveniently. Details of the flow-through detector and its performance when used for the determination of the respective ion of interest under different matrices are described. © 2000 John Wiley & Sons, Inc.

一种用于检测奎宁和百草枯的壁式射流检测器

本文综述了在我们的研究实验室中使用的壁式射流型流动检测器分别用于奎宁和百草枯的电位测定。该检测器允许在流动注射分析模式下对聚氯乙烯基膜的分析响应特性进行评估。这种离子选择性电极膜，含有离子交换剂或中性载体类型的电活性组分，与适当的增塑溶剂结合，有时也与其他膜添加剂(如百草枯选择性膜)结合，可以方便地应用于检测器组件。利用流动检测器可以方便地进行抗疟疾药物奎宁和除草剂百草枯的检测研究。描述了流动检测器的细节及其在不同矩阵下用于测定各自感兴趣的离子时的性能。©2000 John Wiley &儿子,Inc。实验室机器人与自动化，2000:133 - 137
