DIN EN 15483-2009环境空气质量.使用FTIR光谱学测量近地面大气环境

This European Standard is applicable to open-path absorption measurements of 'concentration ~ path length'product using the Fourier transform infrared (FTIR) technique with an artificial radiation source. It is applicableto the continuous measurement of infrared active organic and inorganic compounds in the gaseous state inambient air using fixed tropospheric open paths up to approximately 1 km in length and provides a spatialaverage.
