摘要: 为了解决生物医疗、石油化工行业微量乙烯浓度难以检测的问题,采用CO2激光击穿装有乙烯气体的光声池产生光声光谱效应,进行了微量乙烯浓度的检测,设计并优化了光声池尺寸,研究了激光谱线10P(16)和10P(18)与乙烯吸收系数、乙烯气体浓度与光声信号之间的关系。结果表明,光声光谱气体检测系统的共振中心频率为833Hz,品质因数为20.8,光声池常数为2323Pacm/W;当激光功率为3.6W时,在两种激光谱线的照射下,光声信号与乙烯气体体积分数之间均成良好的线性关系,其线性拟合优度分别为0.99744和0.99802,系统的最低检测浓度可达0.9nmol/L。实验结果与理论分析相吻合,验证了光声光谱效应对微量乙烯浓度的检测具有良好的应用价值。

Abstract: In order to solve the problem of ethylene detection of trace concentration in biomedical, petrochemical industry, CO2 laser was used to excite photoacoustic spectroscopy effect in photoacoustic cell for ethylene concentration detection. Parameters of photoacoustic cell was designed and optimized. The relationship between laser lines 10P(16), 10P(18) and ethylene absorption coefficient was investigated, and the link of ethylene concentration and photoacoustic signal was studied. Through theoretical analysis and experimental research, the results show that parameters of photoacoustic system are: center of resonant frequency of 833Hz, quality factor of 20.8, and photoacoustic cell of 2323Pacm/W. When laser power is 3.6W, photoacoustic signal and ethylene volume fraction get good linear relationship under the irradiation of two laser spectrum. Linear fit is 0.99744 and 0.99802 respectively. The minimum detectable concentration of system is 0.9nmol/L. Experimental results and theoretical analysis verify the effect of photoacoustic spectroscopy detection of trace concentrations of ethylene has good appliciation value.
