Описаны преимущества метода рамановской спектроскопии по сравнению с газовой хроматографией. Изучены метрологические характеристики рамановского газоанализатора, разработанного в Институте мониторинга климатических и экологических систем. Проведена серия измерений характеристик трёх имитаторов природного газа с различной концентрацией компонентов газовых смесей. Показано, что рамановские газоанализаторы способны обеспечить высокую точность измерений, близкую к точности газовых хроматографов при анализе компонентов с низкой молярной долей (0,001–0,010 %). Отмечено, что при анализе компонентов с молярной долей в диапазоне 0,01–100,00 % точность предлагаемого рамановского газоанализатора превзошла точность газовых хроматографов.</p></abstract><trans-abstract xml:lang="en"><p>The advantages of the Raman spectroscopy method in comparison with gas chromatography in the analysis of the composition of natural gas are described. The metrological characteristics of a Raman gas analyzer developed at the Institute of Monitoring of Climatic and Ecological Systems of the Siberian Branch of the Russian Academy of Sciences have been studied. A series of measurements were carried out on three natural gas simulators with different concentrations of components. It is shown that Raman gas analyzers are capable of providing high measurement accuracy, close to that of gas chromatographs when analyzing components with a low molar fraction (0.001–0.010 %). It is noted that when analyzing components with a molar fraction in the range of 0.01–100.00 %, the accuracy of the proposed Raman gas analyzer surpassed the accuracy of gas chromatographs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>природный газ</kwd><kwd>метан</kwd><kwd>рамановская спектроскопия</kwd><kwd>газоанализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>natural gas</kwd><kwd>methane</kwd><kwd>Raman spectroscopy</kwd><kwd>gas analysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hippler M., Anal.
