Abstract

A modulated potential pulse-amperometry/coulometry (MPPA/MPPC) method which combines computer-controlled fast modulated potential technique with microelectrode is established for the rapid, simultaneous determination of CO2 and O2 in gas mixtures. Experimental results show that this novel approach can be applied to non-invasive, real-time and dynamic monitoring of respiratory gases CO2 and O2 simultaneously with satisfactory accuracy, response time, detection range and long term stability.
