This Standard sets out the method for the determination of nitrogen dioxide (NO2), sulfur dioxide (SO2) and ozone (O3) found in ambient air using the open-path differential optical absorption spectrometry (DOAS) technique. This Standard sets out performance criteria for these gases, however, the DOAS measurement technique is applicable to other gases. This method can provide a measure of multiple gases integrated over an open-path length of between 100 and 1000 metres.
