一种可用于生物呼吸代谢过程中实时动态联合检测O_2和CO_2的传感技术

A New Transduction Technique for Real-Time and Dynamic Simultaneous Detection of O 2 and CO 2 in Biorespiratory Metabolism Processes

发展并建立了用于快速联合检测Ｏ２和ＣＯ２气体的调制电位脉冲微库仑法．对在非水电化学体系中实现两者一次检测的实时动态传感技术进行了系统研究．结果表明。

Based on the reaction mechanism of both O 2 and CO 2 in the nonaqueous electrochemical system,the modulated potential pulse-microcoulometry is developed. This novel transduction technique,which combined the fast modulated potential pulse method with the microelectrode technique,is evaluated for the detection of both O 2 and CO 2. Results are presented which indicate that the bifunctional electrochemical gas sensor can be suitable for the real-time and dynamic simultaneous monitoring of O 2 and CO 2 in biorespiratory metabolism processes.
