使用多次反射池FTIR系统在2010年12月对浙江地区两种挥发性气体乙炔(C_2H_2)和乙烷(C_2H_6)进行了监测,通过对测量气体的吸收光谱进行光谱定量分析,获取了这两种组分的浓度信息,并分析了它们的相关性。研究结果表明,该测量系统能以非接触的方式对空气中多种气体进行在线监测,及时反应测量区域内浓度信息。
C_2H_2 and C_2H_6 are continuously monitored with multi-reflected White cell Fourier transform infrared(FTIR) spectrometer in Zhejiang region in December 2010.The concentration of component information is obtained by measuring gas atmospheric absorption spectra and the correlation between C_2H_2 and C_2H_6 concentration is also analyzed.The results show that the non-contact measurement system can realize online monitoring a variety of gases in the air and reveal the concentration information of measured region in time.
