摘要
本文介绍了排放气体组分浓度分析仪的原理和国内外该仪器的性能指标.国内分析仪器厂在引进国外技术后已能提供符合需要的成套分析系统.我们实验室对用富里叶光谱仪用于浓度检测作了可行性试验,证实可以一次取得各组分浓度数据.对 CO 和 CH 国内能提供标准样气的组分得到的标准曲线,精度优于5%.
The priciples of exhaust gas analysers and technical performance and specifications of national and forign made instruments are described in this paper.National factories have ability to supply complete multi-gas anaytical system satisffied for the vehical service and demands of end line inspection,after the recent import of forign advanced technology. Our laboratory carried out a feasibility experiment of another method of measuring exhaust emissions using IR-FT spectroscopy.The results showed that the measuring errors from the calibrated curves for CO and CH components are better than±5% and concen- tration data of all components can get in one test simultaneously
