SRA R990 MicroGC
Technology: Laboratory


Powerful and versatile micro gas chromatograph


An attractive design and a wide potential of use, there are the main features of the new R-990 designed by SRA Instruments. This powerful gas analyzer uses the latest gas chromatography miniaturization technologies, developed by Agilent Technologies, to perform gas mixture analyzes in less than 3 minutes. This µGC is perfect to be used in the laboratories, in research or production departments with a particular aptitude to continuous analysis of process gases in gas distribution systems, pilot plants or small reactors.

The system, available in desktop or rack cabinet version, is compact in its hardware organization but modular in the choice of the analysis configuration. R-990 incorporates an on-board computer with Windows 10 operating system and chromatographic and process software; a bright and large LCD video with touch screen offers an easy-to-use feature necessary for those who have to manage the start of analysis, instrumental diagnostics and measurement results.
