严重的环境气体污染对多组分气体分析仪提出了实际需求。受通用化设计目的和商用软件功能不健全的限制,传统FTIR光谱仪长期徘徊在气体分析领域的外围。对此,研究了用磁编码信号取代传统FTIR光谱仪中激光干涉信号实现动镜扫描和光谱采集,使所研制的多组分气体分析仪在满足光谱测量的前提下,结构上更加紧凑简洁,调试更为方便;同时针对现场分析的连续性和实时性要求,将经典最小二乘法做了修正,使其获得基线补偿能力。实验表明,所研制的FTIR多组分气体分析仪具多组分气体的快速、连续准确的定量能力,可对环境污染气体有效监测。

The frequent environmental events abo ut the polluted gases ask for some kinds of multi-gases analyzer. Limited to the general aim of design and incomplete function in software, the conventional Fourier Transform Infrared spectrometer can′t be effectively involved in the field of gases analysis. To solve this problem, a new method was studied using the magnetic encoded signal to drive the moving cube and collect the spectrum data, instead of the conventional laser interference signal. It was in this way that a concise structure of analyzer was established and it facilitated the procedure of debugging and setting-up. At the same time, in order to meet the demands of continuous and immediate analysis, an improved quantitative algorithm with the ability of baseline compensation automatically was illustrated. The related experiments with the designed gases analyzer which is verified to be an effective tool for environmental gases monitoring can execute the multi-gases quantitative analysis rapidly and continuously.
