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.
