摘要：

An amperometric sensor array has been interfaced to a catalytic microreactor. The apparatus has been automated so that frequency- and amplitude-modulated concentrations can be produced for subsequent detection by the sensor array. The response of the CO sensor to modulated concentrations of CO, benzene, TCE, formaldehyde and perchloroethylene has been studied at different frequencies. The results reveal the operating principles and suggest that a simplified modulator-sensor system may provide enough information to identify and quantify individual compounds in simple mixtures. © 1990.
