摘要：
We have developed a spectrometer designed to record spontaneous Raman scattering (SRS) spectra in gaseous media. The spectrometer has improved sensitivity due to using a high-performance spectral instrument and also a device for compressing the analyte gaseous medium. We present the results of an experimental test of the spectrometer, and show that its limiting sensitivity for methane is < 1 ppm.
