Journal ArticleDOI
Beat frequency quartz-enhanced photoacoustic spectroscopy for fast and calibration-free continuous trace-gas monitoring.
Hongpeng Wu,Lei Dong,Huadan Zheng,Huadan Zheng,Yajun Yu,Weiguang Ma,Lei Zhang,Wangbao Yin,Liantuan Xiao,Suotang Jia,Frank K. Tittel +10 more
TL;DR: The BF-QEPAS method is capable of measuring lower trace-gas concentration levels with shorter averaging times as compared to conventional PAS and QEPAS techniques and determines the electrical QTF parameters precisely.
Journal ArticleDOI
Quartz enhanced photoacoustic H2S gas sensor based on a fiber-amplifier source and a custom tuning fork with large prong spacing
Hongpeng Wu,Angelo Sampaolo,Angelo Sampaolo,Lei Dong,Lei Dong,Pietro Patimisco,Xiaoli Liu,Huadan Zheng,Xukun Yin,Weiguang Ma,Lei Zhang,Wangbao Yin,Vincenzo Spagnolo,Suotang Jia,Frank K. Tittel +14 more
TL;DR: In this article, a fiber-amplifier-enhanced photo-acoustic spectroscopy (QEPAS) sensor with an acoustic micro-resonator (AmR) was used for H2S trace gas detection.
Journal ArticleDOI
Atmospheric CH4 measurement near a landfill using an ICL-based QEPAS sensor with V-T relaxation self-calibration
Hongpeng Wu,Lei Dong,Xukun Yin,Angelo Sampaolo,Pietro Patimisco,Weiguang Ma,Lei Zhang,Wangbao Yin,Liantuan Xiao,Vincenzo Spagnolo,Vincenzo Spagnolo,Suotang Jia +11 more
TL;DR: In this paper, a quartz-enhanced photoacoustic spectroscopy methane (CH4) sensor with vibrational to translational (V-T) relaxation self-calibration was realized and tested for atmospheric CH4 detection near a landfill.
Journal ArticleDOI
Coal analysis by laser-induced breakdown spectroscopy: a tutorial review
Sahar Sheta,Sahar Sheta,Muhammad Sher Afgan,Zongyu Hou,Shunchun Yao,Lei Zhang,Zheng Li,Zhe Wang +7 more
TL;DR: In this paper, the authors present a comprehensive review of the use of laser-induced breakdown spectroscopy (LIBS) for coal analysis, including fundamentals and key factors, operation modes, data processing and analytical results.
Journal ArticleDOI
Single-tube on-beam quartz-enhanced photoacoustic spectroscopy.
Huadan Zheng,Lei Dong,Angelo Sampaolo,Hongpeng Wu,Pietro Patimisco,Xukun Yin,Weiguang Ma,Lei Zhang,Wangbao Yin,Vincenzo Spagnolo,Suotang Jia,Frank K. Tittel +11 more
TL;DR: Quartz-enhanced photoacoustic spectroscopy with a single-tube acoustic microresonator inserted between the prongs of a custom quartz tuning fork was developed, investigated, and optimized experimentally, improving the detection sensitivity and facilitating the laser beam alignment.
