Assessment of Jetanizer and Quantitative Analysis of CO₂ and CH₄ in the Atmosphere

User Benefits

- Simplification of the analytical system for CO and CO₂ utilizing the Jetanizer coupling with GC-FID. - Low-cost system achieved with adding the Jetanizer to FID-2030 that is already working. - N₂ as carrier gas available.

Introduction

More and more research and development projects are focusing on being “Carbon Neutral”, which is the pursuit of zero Greenhouse gas production from human industrial activity. Greenhouse gas includes Carbon Dioxide (CO₂) and Methane (CH₄). In addition, high-purity hydrogen requires high-sensitive analytical system for the impurities such as CO, CO₂, and CH₄. Therefore, easy quantification methods for these gases are required in various fields for becoming “Carbon Neutral”. While TCD and BID are excellent for the analysis of inorganic gases, they both have difficulties with these applications. Highly sensitive analysis is not possible in TCD, and carrier gas is limited to Helium in BID. A methanizer can be installed to utilize FID for CO and CO₂ analysis. A traditional methanizer uses a Nickel (Ni) catalyst in a hydrogen rich environment to reduce CO and CO₂ to CH₄ for analysis by FID. This setup requires an additional heater and gas line for installation. The Ni catalyst is also highly sensitive to oxidation by oxygen. The Jetanizer uses a novel, oxygen durable catalyst in the FID nozzle. The hydrogen for the FID flame provides the hydrogen rich environment for reduction and the FID heater is utilized for heating the catalyst. Thus, the whole system is durable for oxygen, simple to install, and can expand its usefulness to wider fields. This article introduces how the Jetanizer on the GC-2030 is useful for analysis of CO, CO₂ and CH₄.
