Abstract
Electrochemical devices have found very wide application in the field of toxic gas monitoring in the context of industrial hygiene. Until about 10 years ago they had not been as widely used for stack gas or exhaust monitoring with the exception of the zirconia sensor for oxygen. However, there are now many portable flue gas analysers based on these cells offering the potential to measure up to about six gases in one unit. There are no problems with sensitivity to the pollutant gases found in flue gases since the concentrations are generally higher than in ambient factory atmospheres. However, there may be more severe problems of selectivity, resistance to contamination and operational life than would be encountered in industrial hygiene applications.
