| 摘 要： | 基于非水介质中O2和CO2共存时的交叉反应动力学特性,结合微电极电化学检测技术,构建了暂态电化学多组份气体传感器系统.该系统既保持了电化学传感器的优点,又具备数字信号的远程传输能力,将单个气敏电极对多组份气体交叉敏感的致命缺陷转化为快速、同时检测多组份混合气体的动力学条件加以利用,用单个气敏电极实现了气调储粮中O2和CO2的快速检测.

| Abstract: | Based on studying the kinetic characteristics of cross reactions for coexisting multicomponent gases O2 and CO2 in non-aqueous media,using single working microelectrode,a kind of transient electrochemical multi-component gas sensor system has been designed and constructed.This multi-sensor system not only keeps the advantages of electrochemical sensors,but also fuses the knowledge and technology of computer science and long-distance transmission,thus convering the fatal defect of cross-sensitivity to multi-... |
