摘要
综述了近些年来国内外痕量气体浓度检测技术研究的最新进展。首先对传统的非光学气体浓度检测技术作出了简单的介绍,包括超声波技术、气敏法、热催化法、气相色谱法、干涉法应用技术,被动检气管法,然后重点阐述了基于光谱学分析气体浓度检测技术的最新发展动态,其中分别对差分吸收光谱技术(DOAS)、傅里叶变换红外光谱技术(FTIR)、可调谐激光二极管激光吸收光谱技术(TDLAS)、差分吸收激光雷达(DIAL)和拉曼散射激光雷达、激光诱导荧光光谱技术、激光光声光谱技术进行了详细介绍,最后提出了现代气体浓度检测技术的发展方向。
The latest progress of trace gas concentration detection technology is reviewed. First the traditional non-optical detection technology for gas concentrations is briefly introduced, such as ultra-sound technology, gas sensing, catalytic thermal, gas chromatography, interferometry applications, and then the spectral analysis based on the concentration of gas detection is discussed. The latest technological developments on the differential absorption spectroscopy, Fourier transform infrared （FTIR） spectroscopy, tunable laser diode laser absorption spectroscopy （TDLAS）, laser radar and differential absorption Raman scattering laser radar, laser -induced fluorescence spectroscopy, laser Photoacoustic Spectroscopy are reviewed in detail. The development direction of modern gas concentration detection technology is prospected.
