В качестве аналитической выбрана линия углерода в ближней ИК области С I 909.483 нм. Проведена оптимизация условий регистрации спектра в указанной области. Показано, что переход к двухимпульсному режиму возбуждения увеличивает интенсивность спектральных линий элементов, входящих в состав анализируемого образца, и снижает интенсивность линий элементов, входящих в состав воздуха, что позволяет вести анализ по данной линии при нормальных атмосферных условиях. Построенная калибровочная зависимость для углеродистых сталей имеет линейный характер для практически важного диапазона концентраций определяющего компонента этого сорта сталей. Проведена оценка погрешности измерения концентрации углерода, а также уровня влияния на его определение загрязнений этим элементом атмосферы рабочей среды.</p></abstract><trans-abstract xml:lang="en"><p>Based on laser atomic emission spectroscopic analysis, a technique has been developed for the rapid determination of carbon content in low-alloy steels. The C I 909.483 nm carbon line in the near infrared region of the spectrum was chosen as an analytical one. Optimization of the conditions for the spectrum recording in this region is carried out. It is shown that the transition to a double-pulse mode of excitation enhances the intensity of the spectral lines of the elements included in the composition of the analyzed sample, and reduces the intensity of lines of the elements included in the composition of the air, which allows the analysis of the line under normal atmospheric conditions. The calibrated dependence for carbon steels is linear for the practically important concentration range of the determining component of this steel grade. The measurement error of the carbon concentration, and also the influence of pollution of atmosphere of a working environment by this element on its determination are estimated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лазерная атомно-эмиссионная спектроскопия</kwd><kwd>двухимпульсный режим</kwd><kwd>сталь</kwd><kwd>углерод</kwd><kwd>laser atomic emission spectroscopy</kwd><kwd>double-pulse regime</kwd><kwd>steel</kwd><kwd>carbon</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">E.
