激光拉曼光谱气体分析的研究
Preliminary Study on Gas Analysis by Laser Raman Spectroscopy
摘要
Abstract
A stable laser Raman spectrum baseline was obtained by improving and optimizing the performances of the laser Raman spectrometer. The effects of environmental temperature,integration time and test pressure on the Raman signals were investigated. 6 Basic components in pyrolysis gas, namely H2,CH4,C2H4,C2H6,C3H6 and C3H8,were determined by means of the laser Raman spectrometer. It was showed that,under the optimal conditions of environmental temperature 23.5℃,integration time 25 s and test pressure 0.5 MPa,the results analyzed by GC and the laser Raman spectrometer were roughly equivalent,and all the relative standard deviations of the two methods were smaller than 2%,which meant the established Raman analysis method had good repeatability. Compared to the GC analysis,the laser Raman spectroscopy can improve the data feedback speed and reduce the analysis cost.关键词
