  • An ultra-sensitive detection system for sulfur dioxide and

    2020-6-5A highly sensitive detection system for sulfur dioxide (SO 2) and nitric oxide (NO) was developed via deep ultraviolet differential optical absorption spectroscopy (DUV-DOAS).The wavelength range of 200–230 nm was used which was rarely used before as result of severe cross sensitivity to SO 2 and NO, in this work, this problem was overcame. A system detection limit (DL) of 60 ppb for SO 2Author: Bo Peng, Yong Zhou, Guoqing Liu, Yong He, Chao Gao, Yongcai Guo
