摘要
为了检测、分析混合气体, 根据混合气体中不同气体成分在喇曼频谱中各自的吸收谱峰, 采用激光谐振腔增强光谱法原理和喇曼散射光谱技术, 利用有源激光谐振腔和雪崩光电二极管, 设计了针对于混合气体成分进行在线分析的实验系统。结果表明, 对混合气体进行实时在线检测, 可以有效检测出包含体积分数分别为0.502, 0.498的N2和O2的混合气体。该系统操作便捷、安全可靠, 可以实现混合气体的成分分析。
Abstract
In order to detect and analyze the mixed gas, according to specific absorb spectrum peak of different kinds of gas in the mixed gas, based on the theory of laser resonant cavity enhanced spectroscopy and the technology of Raman scattering spectrum, and using active laser resonant cavity and avalanche photodiode, an online analysis system of the composition of the mixed gas was designed. Experimental results show that real time on-line detection of mixed gas can be realized and the mixed gas containing volume fraction of N2 and O2, respectively 0.502 and 0.498, can be detected effectively. The system is convenient, easy, safe, and reliable for operation. And the system can be used to detect the composition of the mixed gas.
