ENVIRONMENTAL AND POLLUTANTS GAS ANALYZERS

Ana Madeira, Florbela A. Dias, Eduarda Filipe

Abstract

Air pollution exists where there are quantitative variations in the air composition or by the introducing of new pollutants. With the automobiles and industrialization increase there has been a need to control gas emissions before loading them into the environment. To this end, environmental and pollutants gas analyzers are used and it is necessary calibration by competent entities.<br />The main proposal of this communication is to demonstrate the importance of the calibration operation of these instruments as well as the calculation of associated uncertainties.
