Process Gas Chromatographs

GC8000 Banner

Process gas chromatography is used for separating and analyzing chemical compounds in the gas phase of industrial processes. Gas chromatograph instruments vaporize and distribute samples between a stationary and mobile phase, whereby a chemically inert gas carries molecules through a heated column.

Yokogawa gas chromatographs provide reliable and precise process analysis, with touch screen operation for effortless results. All chromatograph settings, displays, and data are truly segragated for easy understanding and maintenance. Since 1959, Yokogawa has supplied GC solutions to the oil & gas, refining and petrochemical industries around the world. Over the past 50 years, the GC products of Yokogawa have continued to evolve to meet the ever changing needs of the process industry.

  • Gas Chromatograph AI Maintenance Support (GCAI) for GC8000

    GCAI software uses machine learning models built for each monitored GC8000 to detect "unusual" measurement conditions in real-time.
    The system helps you deal with malfunctions in advance and realize prompt maintenance response in the event of a malfunction.
    User can start to use by setting-less.

Overview:

High volumes of volatile organic compounds (VOCs), typified by trichloroethylene and tetrachloroethylene, have long been used in various industrial fields for their high degrees of industrial usefulness. On the other hand, there is a growing awareness of environment preservation today, and of the fact that we face serious environmental pollution due to such harmful VOCs.

Yokogawa Technical Report
Overview:

In recent years, shale gas extraction technology has made rapid progress, inducing a shale gas revolution mainly in the USA. Thus, the need for analysis of hydrocarbon gases, including natural gas, is expected to grow rapidly. Traditionally gas chromatography has been used for the analysis of hydrocarbon gases; it can accurately measure the concentration of each hydrocarbon component in a sample of natural gas.
