摘要:

随着工业制造、医学诊断和环境监测等领域的快速发展,对有毒有害、易燃和混合气体等检测需求日益增长。 硫化氢(H2S)、二氧化氮(NO2)和甲烷(CH4)等有害气体即便在低浓度下也能对人体健康构成威胁。 因此,在环境监测和工业制造生产中,对痕量气体的检测变得至关重要。 本综述聚焦于近年来气体检测领域的最新研究进展,对比分析了传统气体检测技术和光学气体检测技术,并特别强调了光学检测技术的最新发展。 光学检测技术以其高效率、多组分检测能力及高灵敏度等优势受到更多关注。 本文详细介绍了包括可调谐二极管激光吸收光谱(TDLAS)、拉曼光谱、傅里叶变换红外光谱(FT-IR)和光声光谱(PAS)的工作原理及应用进展,并对气体检测技术的未来发展方向进行了分析和展望。

Abstract:

With the rapid development of industrial manufacturing, medical diagnosis and environmental monitoring, the demand for detection of toxic and harmful, flammable and mixed gases is growing. Harmful gases such as hydrogen sulfide (H2S), nitrogen dioxide (NO2), and methane (CH4) can pose a threat to human health even at low concentrations. Therefore, the detection of trace gases has become very important in environmental monitoring and industrial manufacturing. This review focuses on the latest research progress in the field of gas detection in recent years, compares and analyzes the traditional gas detection technology and optical gas detection technology, and especially emphasizes the latest development of optical detection technology. Optical detection technology has attracted more attention because of its advantages such as high efficiency, multi-component detection ability and high sensitivity. This paper introduces in detail the working principles and application progress of typical gas optical detection technologies, including tunable diode laser absorption spectroscopy (TDLAS), Raman spectroscopy, Fourier transform infrared spectroscopy (FT-IR) and photoacoustic spectroscopy (PAS), and conducts an analysis and outlook on the future development direction of gas detection technology.

Key words: Gas detection, Tunable diode laser absorption spectrum, Photoacoustic spectroscopy, Fourier transform infrared spectrum, Raman spectroscopy
