基于气体相关滤波技术的非分散红外CO气体监测系统的研究
Non-dispersive infrared instrument based on gas filter correlation technology for atmospheric CO monitoring
摘要
介绍了一种有效的测量CO气体浓度的方法-基于气体相关滤波技术(GFC)的非分散红外法(NDIR),以及该方法在实际测量中的应用.根据该方法设计出新型CO监测仪,实验表明,设计的基于GFC技术的非分散红外CO监测系统在0～200 ppm的测量范围内有10 ppb的监测精度.
Abstract
A novel method-non-dispersion infrared (NDIR) based on gas filter correla-tion(GFC) technology for measuring CO trace gas and its application in the field measurement were described. We designed new instrument for CO measurement. The results show that the design and techniques applied in this study are effective in practice. 0.01 ppm resolution in the measure range from 0 to 200 ppm was realized.
