摘要： A method of simultaneously measuring the quantitative presence of a plurality of atmospheric pollutants and apparatus for performing the measurement is disclosed. Specific dry reagents which react with particular pollutants to be measured are exposed in a staged array according to their reactivity to a known volume of ambient air at a location to be measured. The reaction products are later analyzed to obtain a quantitative measure of the pollutants present in the sample.
