Restek Methanizer for Shimadzu GCs
Installation/Operation Guide*

1.0 Overview

The Restek methanizer enables a flame ionization detector (FID) to detect low levels of carbon monoxide (CO) and carbon dioxide (CO ). The
2
gas mixture is first separated using a GC column, and then it passes over a hot catalyst that (in the presence of hydrogen) converts any CO
and CO into methane. Methane (CH ) is readily detected by the FID. A typical setup is shown in Figure 1.
