As the interest in ultrafine particle increases, researches on the mechanism of the secondary fine particle, which is generated by chemical reaction with other materials in the air, are active. Most of secondary fine particles are produced by the main generation mechanism with nitrogen oxides (NOx, NO & NO₂). The NOx is generated by energy and power plant systems in our surrounding such as vehicle, exhaust, power plant, and incineration plant, etc.. Normally, NOx is measured by the chemiluminescent method specified by clean air conservation act. However, this method can measure not each molecule such as NO, NO₂ but total NOx only. Therefore, for analyzing reaction accurately, both NO and NO₂ must be analyzed in real time, and the absence of such technology is the one of the reasons that has a limitation of the secondary fine particle generation mechanism analysis.
In this paper, NO and NO₂ gas concentrations have been measured separately with multi-line strength absorptions using quantum cascade laser (QCL) in the mid-infrared region. At this time, The center wavelengths of the lasers used are 1851 cm<SUP>-1</SUP>(NO gas) and 1612 cm-1 (NO₂ gas).
