This application note describes a method for high-resolution analysis of refinery gas using an Agilent 7890A GC. The method uses a triple detector configuration, including an FID, a TCD (using nitrogen or argon as the carrier gas) and a TCD (using helium as the carrier gas). This method allows analysis of a variety of components, including permanent gases, hydrocarbons and sulfur compounds, in 6 minutes.
This document details a method for the high-speed analysis of refinery gas using a single Agilent 7890A gas chromatograph equipped with three parallel detection channels. The system utilizes a packed column and a PLOT alumina column to separate light hydrocarbons and permanent gases within 6 minutes. A third channel with a TCED (Thermal Conductivity Electron Detector) using nitrogen or argon carrier gas is employed to improve the sensitivity and linearity for hydrogen analysis. This manual is written in Japanese.
