Raman analyzer for sensitive natural gas composition analysis

Raman spectrum of ethane in methane environment

“…To date, application of Raman gas analysis is actively developed due to appearance of highly sensitive multichannel detectors, holographic, and fiber optics, as well as relatively inexpensive lasers operating in the visible wavelength range, combining reliability, compactness, and high output power. In turn, one of the most promising fields of Raman gas analysis application is the diagnostics of natural gas (NG) composition . On the one hand, Raman spectroscopy has the numerous advantages as compared to the traditional gas chromatography.…”

“…In turn, one of the most promising fields of Raman gas analysis application is the diagnostics of natural gas (NG) composition. [1][2][3][4][5][6][7] On the one hand, Raman spectroscopy has the numerous advantages as compared to the traditional gas chromatography. Among them, there are relatively fast analyses results, simultaneous monitoring of all molecular components whose content exceeds the sensitivity threshold of the equipment, lack of consumables, etc.…”

A Method for the Quantitative Analysis of a Key Component in Complex Mixtures Using Raman Spectroscopy Based on Peak Decomposition

“…[1][2][3][4][5][6][7] Recently, it has been increasingly used, and has played an important role for the online monitoring of industrial production processes. [8][9][10][11][12][13][14][15][16] Raman spectroscopy has the advantages of fast speed of data acquisition, few requirements of sample pre-processing and realizes non-invasive detection.…”

Спектры Комбинационного Рассеяния Н-Бутана, Изобутана, Н-Пентана И Изопентана В Среде Метана

“…и неуглеводородных соединений, таких как азот, водород и диоксид углерода. Несмотря на широкое распростране-ние газовых хроматографов для определения состава ПГ, достаточно многообещающим на сегодняшний день вы-глядит применение газоанализаторов, основанных на спектроскопии комбинационного рассеяния (КР) све-та [1][2][3][4][5][6][7][8]. Основными преимуществами КР газоанализато-ров являются высокая скорость измерений, отсутствие расходных материалов, а также возможность одновре-менного контроля всех молекулярных составляющих газовой среды, концентрация которых превышает порог чувствительности аппаратуры.…”
