This application brief describes a configuration of Agilent 7890A GC with three parallel channels and a TCD detector that provides complete refinery gas analysis (RGA), including nitrogen, hydrogen, oxygen, carbon monoxide, carbon dioxide, hydrogen sulfide, and methane, on one instrument.
This document describes an application using the Agilent 7890A Gas Chromatograph configured with three parallel channels to perform complete refinery gas analysis (RGA) in approximately six minutes. The setup includes one FID channel and two TCD channels, utilizing specific columns and carrier gases for simultaneous detection of hydrocarbons, permanent gases, hydrogen, and sulfur compounds.
The total run time is less than 6 minutes.
It conforms to ASTM D1945, D1946, and UOP 539.
The lowest detection limit is 50 ppm for all compounds.
