摘要
An on-line instrument has been developed for the determination of the nitrogen concentration in natural gas. The instrument is based on Raman scattering of laser light. The mean error and the standard deviation of the error of the instrument is better than plus or minus 0. 2% resp. 0. 1%, while the response time is less than 10 seconds. By replacing an optical filter, the instrument can also determine the concentrations of other molecular components.
