    Resum:
    Featured Application The Developed Raman Laser Gas Spectrometer is Suitable for Detection of Carbon Isotopologues of Methane and Carbon Dioxide in Human Exhalation. A compact Raman laser gas spectrometer is developed. It comprises a high-power green laser at 532.123 nm as an excitation source and a specially designed gas cell with an internal volume of less than 0.6 cm(3) that can withstand gas pressures up to 100 atm. The resolution of the spectrometer is similar to 1 cm(-1). The Raman spectra of chemically pure isotopically enriched carbon dioxide ((CO2)-C-12, (CO2)-C-13) and methane ((CH4)-C-12, (CH4)-C-13) gases are studied. The expected limit of detection (LOD) is less than 100 ppm for the isotopologues of CO2 and less than 25 ppm for those of CH4 (at a gas pressure of 50 atm.), making the developed spectrometer promising for studying the sources of emissions of greenhouse gases by resolving their isotopologue composition. We also show the suitability of the spectrometer for Raman spectroscopy of human exhalation.
