GC-2030

In-Jet Methanizer for GC-2030

The flame ionization detector (FID) has no response to carbon dioxide (CO2) under normal conditions without conversion to a more suitable compound for detection, such as methane. The In-Jet Methanizer is a catalytic reactor contained fully in the FID jet enabling the accurate analysis of CO2.

  • Converts CO and CO2 to Methane
  • Wide linear range from 0.1 ppm to 100%
  • Unique, 3D printed non-nickel catalyst for more resistance to oxygen and sulfur poisoning
  • Directly replaces existing FID jets; no additional fittings or connections required
  • Uses existing FIG fuel gases; no additional gas flows required
  • Available as a single or multipack
