At least one air pollutant is concentrated at the source from which the sample of air is obtained. The thus concentrated at least one air pollutant is provided through conduits to a central analyzer for analysis. Concentration of the air pollutant results in reducing transport losses and also the sensitivity of the detector utilized to detect the at least one air pollutant can be greatly increased.
