Abstract: Gas chromatography(GC) is currently employed for natural gas composition analysis. It is more complicated and time-consuming for it requires multiple columns and separation analysis steps. Laser Raman spectroscopy is an analysis method by measuring the light scattering signal of the substance, and it has advantages of real-time, simple and fast. Now it had been widely applied in analysis of solid and liquid samples. In this paper, the technical characteristics of existed natural gas composition analysis method was studied and then laser Raman spectroscopy was proposed as a scheme for the rapid analysis of natural gas composition due to its development in gas analysis. This paper also discussed the application of laser Raman natural gas analysis, which would benefit to the development of application laser Raman technology to natural gas analysis. In the aspect of qualitative analysis, the characteristic peaks of hydrocarbon components in natural gas could be quickly and accurately obtained through measuring a specific series of laser standard gas substance. Quantitative analysis was carried out by the external standard method, using natural gas reference material for single point calibration. Two typical natural gas samples were tested by laser Raman spectroscopy, the results showed that Raman spectroscopy and gas chromatography were in the comparable level.
