In-Jet Methanizer
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
