 Aerosol Chemistry 

  Dr. Jinian Shu is a professor of Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, graduating from Anhui University with B. S. in 1988 and from University of Science and Technology of China with Ph. D. in 1998. He worked at Ben-Gurion University, Institute of Atomic and Molecular Sciences, Academia Sinica, and Lawrence Berkeley National Laboratory as a postdoctoral fellow and scientist from 1998 to 2005. Dr. Shu joined Research Center for Eco-Environmental Sciences as a PI in 2005. He has contributed more than 80 research articles to various scientific journals including JACS, Nano Lett, ES&T, Atmos Environ, etc.  

Research interests: (1) Heterogeneous reactions of organic aerosols; (2) Formation of secondary organic aerosols; (3) Development of mass spectrometric instruments for VOCs and aerosols detections.

Development of ultrasensitive VUV photoionization VOC mass spectrometer  

Jinian Shu*, Wanqi Sun, Peng Zhang, and Bo Yang 

  Volatile organic compounds (VOCs) are important atmospheric pollutants. The atmospheric VOCs are involved in the formation of photochemical smog, ground-level ozone, and city haze. Some VOCs such as benzene and its derivatives are well-known carcinogenic substances. However, it is not easy to detect atmospheric VOCs in real-time due to their ppb-level concentrations currently. In 2015, a lamp-based VUV photoionization mass spectrometer (VUV-PIMS) was developed by our group. With the employment of a novel photoionizer consisting of a photoionization cavity and a VUV light baffle, an extremely low background noise level was obtained. An ultrasensitive detection limit, 5 pptv (for benzene in 10 s acquisition time, 2 σ), was achieved. The design and initial experimental results has been published in Atmos. Meas. Tech., 8, 4637-4643, 2015.
