About I-GRAPHX
I-GRAPHX GmbH develops and manufactures high-precision analysis systems based on micro gas chromatography using MEMS technology. The portfolio comprises desktop and rack gas chromatographs, the H2 Purity Analyzer for purities up to 99.999 % (Grade 5.0) with measurement times of under ten seconds, binary and complex gas analyzers, micro-dosing systems (I-DOG), electronic pressure regulators and HMI systems (X-View). Detectors and measuring circuits are in-house developments and are manufactured in the company's own MEMS production processes for miniaturized subsystems. In addition, the company offers engineering for special measurement tasks, sample gas preparation with multi-gas-stream circuits (double block and bleed) as well as purchase and rental models. The systems analyze gases and dissolved gases in liquids in a measuring range from a few ppm to 100 %, including H2, He, O2, N2, CO, CO2, CH4, Ar, NH3, H2S, methanol and ethanol. Fields of application include hydrogen, electrolysis, e-fuels, pyrolysis, fuel cells, carbon capturing and biomass; according to the company, the systems are in use in 26 countries.
