Abstract:

The online gas chromatography analysis is a multidisciplinary area that uses an online sampling system to transfer chemical process materials to a pre-treatment system, in which interference components such as dust and corrosive compounds are removed, then the materials are seat to a gas chromatograph for separation, detection and quantitation. Finally, the chromatographic data is automatically processed, remotely sent, and alarmed through a data processing platform. The online gas chromatography analysis technology has been applied in three aspects, i.?e. micro-reactor, laboratory online analysis, and industrial chromatography. This article reviews the development history of online gas chromatography technology briefly, and the research and applications are also introduced via the authors′ 20-year-experience. Besides, the challenges and opportunities faced by this technique are discussed in detail, and the future development of domestic online gas chromatographic instrumentation is prospected.

Key words: Online gas chromatography, Micro-reactor online gas chromatography, Laboratory online gas chromatography, Process chromatography
