Air quality. Atmospheric measurements near ground with active Differential Optical Absorption Spectroscopy (DOAS). Ambient air and diffuse emission measurements Ingestion-build-63114 It is applicable to all1 Scope This European Standard describes the operation of active DOAS measuring systems with continuous radiation source, the calibration procedures and applications in determining gaseous constituents (e. g. NO2, SO2, O3, BTX, Hg) in ambient air or in diffuse emissions.
