Considering a Jetanizer?JETANIZER
When someone has interest in the Jetanizer, there is usually a common set of questions asked. Sometimes scientists have these questions in mind before talking to a sales engineer, other times they naturally arise. If you are interested in a Jetanizer for CO2, CO, or formaldehyde analysis, then this is the quick article for you.
The Jetanizer is a 3D-printed FID jet loaded with catalyst for methanation. It is designed to turn the traditional Flame Ionization Detector (FID) into a methanizer. The Jetanizer is a simple, easy to replace solution to traditional bulky methanizers.
What is the longevity of the Jetanizer?
The Jetanizer lasts about 6 months or 5,000 injections. This is dependent on the compounds that are being analyzed. Exposing the Jetanizer to ambient air while at 400°C can lead to damage and should be avoided. The catalyst can tolerate air injections for analysis.
What sample matrices should be avoided to reduce potential poisoning of the catalyst?
There is a shortened lifetime of the catalyst caused by high molecular weight hydrocarbons (C6+), alkynes, unsaturated hydrocarbons, and sulfur-containing compounds. These should all be avoided if possible. Avoiding these compounds will extend the life of the Jetanizer. You can use the Jetanizer to backflush to avoid injecting larger compounds.
What is the sensitivity of the Jetanizer-FID for CO, CO2, and formaldehyde?
The sensitivity is that of your FID for methane. A variety of factors can impact sensitivity or LOD, such as baseline noise and separation resolution. We have quantified concentrations less than 1 ppm for CO, CO2, and formaldehyde . Detection limits for CO & CO2 have been as low as 100 ppb .
Which Jetanizer model is compatible with my GC?
For a Shimadzu 2010 or 2030 GC, use JT-SHZ-CP1. For Agilent Intuvo, 8890, or 8860 GCs, use JT-INT-PK1. For Agilent 5890, 6890, or 7890 GCs, it will be dependent on the FID connection type. There are three options available determined by the following information. If you are using a capillary column with an adaptable FID fitting, JT-ADC-PK1; a packed column with an adaptable FID fitting, JT-ADP-PK1; or a capillary optimized FID, JT-CAP-PK1.
