内容 ln the first part of speech, with a description of the principle of DOAS (Differential Optical Absorption Spectroscopy), the design and realization of two different kinds of DOAS systems are nresented. 0ne is using a slotted disc raoid scanning device with a photomultiplier, which is suitable for ambient air quality measurement. It can measure total 16 kinds of pollutants such as SO_2, NO, N02, NH_3, O_3, C_6H_6, C_7H_8 and CH_2O etc., with detection limits of 1-2ppb. The other is using a UV grating monochromator with a PDA (Photon Diode Array) detector, which is designed for continuous chimney emission monitoring. Its measuring range for SO_2, NO, NO_2 and NH_3 are from 10 to 5000ppm. Diagrams of two systems and some measured results are also shown respectively. ln the second part of speech, recent environmental monitoring technique developments in Anhui Institute of Optics and Fine Mechanics, the CAS are briefly introduced, including mobile pollution monitoring lidar and some other point sampling analyzers for air quality measurement of S0_2, NOx, and TSP/PMIO.
