Jetanizer - Features
A Methanizer in an FID Jet for Gas Chromatography
High Performance
Low-level detection of CO and CO2 is important in catalysis, hydrogen (H2) purity analysis, dissolved gas analysis (DGA), greenhouse gas (GHG) analysis, transformer oil gas analysis (TOGA), ethylene/propylene monomers, safe entry analysis, and more. Conventionally, large nickel-catalyst-filled tube methanizers are used; however, they are prone to frequent failures and they are difficult to operate and maintain. Shimadzu’s Jetanizer solves these challenges by incorporating state-of-the-art catalysts into an FID jet. Moreover, the Jetanizer enables low level <1 ppm formaldehyde analysis by GC avoiding the pitfalls of HPLC analysis of formaldehyde.

More straightforward and highly sensitivity
- Ability to be used with formaldehyde
- Higher catalytic activity = larger linear dynamic range
- No toxic metals: The Jetanizer does not contain nickel catalysts
Cost, time, space saving
- Lower up-front cost
- No extra plumbing: minimize fittings and leaks
- No extra heater or controller: utilizes heat from FID
- FAST installation: Less than 5 minutes
- Frees up space on the GC
