During industrial process of gas monitoring, gas pumps are typically used for extract gas dynamically. In order to improve the response time of system, high flow rate pumps are used to draw gases under detection into the gas cell, and therefore, the airflow during monitoring has an impact on system stability. In this paper, we firstly optimize the design of absorption cell through software simulation, so as to improve the airflow stability at high flow rate. And secondly, the normalization algorithm is used to try to suppress the influence of airflow fluctuation on the stability. Finally, we built a dynamic methane measurement system, and the results of normalized and un-normalized concentrations over time were provided for comparison, respectively. The experiment results show that under the flow rate is 34L/min, the response time is 1.2s, and after normalized treatment, the stability is improved from 2.68ppm to 0.64ppm (1σ).
