摘要
本文描述一种同时使用吸收法与荧光法并且能同时测量气体介质中NO和SO2浓度新的方法。该方法具有比吸收法更高的灵敏度,利用该方法研制的仪器采用连续谱的辐射源和低分辩率的单色仪,调试操作简单,可连续长期稳定地工作。经改进后可成为一种适合于燃烧监测用的在线浓度分析仪。
A novel method of measuring the NO and SO 2 concentration in gaseous mediums based on the simultaneous usage of the absorption method and the fluorescence effect has been investigated. The suggested method has advantages of higher sensitivity in relation to the NO concentration and less sensitivity to the nonselective absorption and minimum requirement of the device system. It will be probable to use the device as a line gas analyzer for simultaneous monitoring concentrations of the NO and SO 2 of flue gas from a combustion system.
