Abstract

The hardware design of a Fourier Transform Infrared (FTIR) analyzer was improved to realize the simultaneous and continuous measurements of greenhouse gases and

values in high Precision. Firstly

the FTIR measurement system was designed and analyzed theoretically

and the temperature and pressure monitoring systems and sealed drying gas circuit were introduced into the spectroscopy. Then the process of quantitative spectral analysis was presented. Finally

the comparative measurements were designed by using standard gases. Experimental results on CH

and

indicate that the Standard Deviations(STD) measured by the designed analyzer are 0.01

0.011

0.239 10

-6

and 0.572

the standard uncertainty of designed measurement system is improved about 6.3

8.45

10.54 and 14.73 times that of routine FTIR measurements

and the system errors are improved about 2.88

1.93

4.67 and 4.66 times

respectively. The comparison of the measurement results between the analyzer and the Isotope Ratio Mass Spectrometer (IRMS) for

value shows that the STDs are 0.572 and 0.171 respectively

and the standard uncertainty of the both methods is similar. The FTIR analyzer for greenhouse gases and carbon isotope ratios satisfies the requirements of measurements for multi-species

online and high precision.
