Air quality. Atmospheric measurements near ground with active Differential Optical Absorption Spectroscopy (DOAS). Ambient air and diffuse emission measurements Ingestion-build-63114 BS EN 232 applies to1 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.
