摘要

为了研究六氟化硫（SF

）气体分子和水汽（H

O）对一氧化碳（CO）气体分子的弛豫率的影响，建立了一个基于石英增强光声光谱（QEPAS）技术的痕量气体传感器系统。采用1.57

m的近红外分布式反馈二极管激光器作为激励光源，并对不同SF

和H

O气体浓度下的CO的光声信号进行对比研究。首先用CO传感器系统探测CO与N

的气体混合物中CO的光声信号，然后在CO与N

气体混合物中加入不同浓度的SF

气体，分别探测不同浓度SF

气体下的CO光声信号强度。最后在CO与N2的气体混合物中加入不同浓度H

O，探测加入H

O后的CO的光声信号强度。实验结果表明随着CO和N

气体混合物中SF

气体浓度的增加，CO的光声信号幅值几乎没有变化，而在混合物中加入2.5%的H

O后，发现CO的光声信号提高了约5倍。因此，SF

对CO气体的弛豫率没有明显的影响，然而H

O的添加能够有效缩短CO气体的弛豫时间。

Abstract

A CO sensor system based on quartz-enhanced photoacoustic spectroscopy technology was established to study the effect of sulfur hexafluoride (SF

) and water vapor (H

O) on the relaxation rate of carbon monoxide (CO) gas molecules. A 1.57

m near-infrared distributed feedback diode laser was used as the light source to compare the photoacoustic signal amplitudes of CO under different concentrations of SF

and H

O. First

a CO sensor system was used to detect photoacoustic signals from CO in a gas mixture of CO and N

. Then

different concentrations of SF

gas were added to the CO and N

gas mixture and the photoacoustic signal amplitudes of CO were detected. Finally

O was added to the gas mixture of CO and N

before detecting the photoacoustic signal amplitudes of CO. The experimental results show that with increasing concentration of SF

in the gas mixture of CO and SF

the photoacoustic signal of CO remains constant; however

the addition of 2.5% H

O to the mixture results in a five-fold increase of the photoacoustic signal of CO. Therefore

O has an obvious effect on the relaxation rate of CO gas

while SF

has none.
