An introduction to… Continuous gas monitoring via GC


Permanent gas analysis finds a wide range of applications in the fields of petrochemicals, chemicals, and wider energy industries. Permanent gases such as oxygen, carbon dioxide (CO2), nitrogen, argon and methane (CH4) are common in pure gas manufacturing, refinery gases, natural gas, fuel cell gases, and many other industrial processes.

Automatic identification and quantification of the concentration of these components can be important for controlling manufacturing processes and production quality. In this article, we describe two applications: the continuous monitoring of argon, oxygen and nitrogen impurities in pure hydrogen, using chromaTCD and the complete analysis of natural gas or biogas using chromEnergy, an instrument from Chromatotec.
