Точность измерений концентрации газов с помощью лазерного спектрометра критически зависит от качества его калибровки. В серийном производстве спектрометров традиционные методы калибровки, требующие участия оператора, приводят к субъективным ошибкам, увеличению времени настройки и нестабильности результатов. В данной работе предложен полностью автоматизированный метод калибровки диодных лазерных абсорбционных спектрометров, исключающий влияние человеческого фактора и обеспечивающий стандартизацию процесса для массового производства. Технология основана на использовании эталонных газовых смесей с точно известными концентрациями, алгоритмов адаптивной настройки лазерных параметров и автоматизированной обработки спектральных данных. Предлагаемый метод автоматической калибровки диодных лазерных абсорбционных спектрометров позволяет стандартизировать процесс для массового производства и повысить надежность измерений для газов CH4, C2H4 и C2H6. Экспериментальная проверка на смесях N₂/CH₄ показала, что данный подход обеспечивает погрешность калибровки не более 2 %, что соответствует требованиям промышленного мониторинга. Применение метода открывает новые возможности для массового производства диодно-лазерных абсорбционных спектрометров. В статье также представлены перспективы развития технологии.

The accuracy of gas concentration measurements using a laser spectrometer critically depends on the quality of its calibration. In mass production of spectrometers, traditional calibration methods that require operator intervention lead to subjective errors, increased setup time, and instability of results. In this paper, a fully automated method for calibrating tunable diode laser absorption spectrometers is proposed, eliminating the influence of the human factor and ensuring standardization of the process for mass production. The method is based on the use of reference gas mixtures with precisely known concentrations, algorithms for adaptive adjustment of laser parameters, and automated processing of spectral data. The proposed method for automatic calibration of tunable diode laser absorption spectrometers allows standardizing the process for mass production and increasing the reliability of measurements for CH4, C2H4, and C2H6 gases. Experimental testing on N₂/CH₄ mixtures showed that the proposed approach provides a calibration error of no more than 2 %, which meets the requirements of industrial monitoring. The method opens up new opportunities for the mass production of diode laser absorption spectrometers. The article also presents the prospects for the development of technology.
