摘要
在中红外区域,有效覆盖了恶臭气体中典型的8种组分的吸收位置。本文采用傅里叶变换红外光谱(Fourier Transform Infrared,FTIR)技术,根据恶臭气体的特征吸收,设计了一种恶臭气体监测仪器,能够自动在线监测待测区域的恶臭气体污染情况。以二硫化碳(CS2)气体为例,对系统的线性度等指标进行研究,通过多次重复性实验,得到整个系统的线性相关系数为0.999。
In the mid-infrared region, it effectively covers the absorption sites of eight typical components of malodorous gases. In this paper, Fourier Transform Infrared(FTIR) technology is adopted. Based on the characteristic absorption of odorous gases, a malodorous gas monitoring instrument is designed to automatically monitor the odorous gas pollution in the area to be measured. Taking carbon disulfide(CS2) gas as an example, the linearity of the system was studied. Through repeated experiments, the linear correlation coefficient of the entire system was 0.999.
