| Abstract: | A FTIR system for the accurate measurement of low concentration NO2 was developed. By using the proposed syestem, the concentration of NO2 in the different standard gas were measured; the standard gas were obtained by dynamic dilution method. It was indicated that the system has a good linear response, thus the calibration equation of the system was established. The comparison test showed that the system is accurate and reliable. The stability study showed that the system has good long-term stability. By using dynamic dilution method based on mass flow controllers, the standard gases with different concentration were obtained. This system has a calibration curve with good linearity. The comparison test shows that the system is accurate and reliable. The stability study shows that the system has good long-term stability. |
