Quantification of H₂ and Hydrocarbons in CO₂ Using TCD-to-Jetanizer-FID Series Connection

User Benefits

- Gas analysis including hydrogen, carbon monoxide, hydrocarbons, methanol, and other species can be conducted. - Nitrogen, an alternative carrier gas to helium, can be used as the carrier gas. - The newly introduced GI-30 automatic gas injector enables automatic and reproducible analysis of gas samples.

Introduction

Carbon dioxide (CO₂), known as a greenhouse gas, is also an abundant carbon resource. Therefore, reactions that reduce CO₂ using, for example, water to convert it into useful compounds are attracting attention from the viewpoint of carbon neutrality. The products include hydrocarbons such as methane (CH₄), alcohols, and carbon monoxide (CO). Hydrogen (H₂) may also be produced as a by-product. In this Application News, we used nitrogen as the carrier gas and connected a TCD and a Jetanizer-FID in series to simultaneously analyze H₂, CO, and light hydrocarbons. By using an inlet split, alcohols such as methanol (MeOH) could also be analyzed concurrently.
