In this work, the design and characterization of a multi-cell capacitively coupled contactless conductivity detection system are described. The operation and simultaneous acquisition from 3 detector cells are demonstrated, however, the system is capable of supplying 8 detection cells and can be easily upgraded to maintain 64 capacitively coupled contactless conductivity detection cells. On performing flow-injection analysis, the system recorded as low as 0.01 mM of acetic acid, phosphoric acid, NaH₂PO_4, and Na₂B₄O₇ solutions in water. The instrument was also capable of recording and distinguishing different mixtures of organic solvents: (a) methanol–acetonitrile, (b) hexane–acetone. The designed detection system is expected to be used coupled with multi-channel separation devices for monitoring simultaneous processes.

基于单芯片的非接触式电导率检测系统，用于多通道分离

在这项工作中，描述了多单元电容耦合非接触电导率检测系统的设计和特性。演示了从3个检测器单元进行的操作和同时采集，但是，该系统能够提供8个检测单元，并且可以轻松升级以维护64个电容耦合非接触式电导率检测单元。进行流动注射分析时，系统记录的乙酸，磷酸，NaH ₂ PO ₄和Na ₂ B ₄ O ₇低至0.01 mM水溶液。该仪器还能够记录和区分有机溶剂的不同混合物：（a）甲醇-乙腈，（b）己烷-丙酮。设计的检测系统有望与多通道分离设备结合使用，以监控同时进行的过程。
