Gas Analysis for CO₂ Conversion Using a GI-30 Auto Gas Injector

User Benefits

- Enables quantitative gas analysis for CO₂-derived methanol synthesis and conversion to hydrocarbons. - Using GC with INJ2-way branch unit allows simultaneous analysis of CO, methanol, and hydrocarbons. - The newly introduced GI-30 automatic gas injector enables automatic and reproducible analysis of gas samples.

Introduction

The catalytic conversion of carbon dioxide (CO₂) to methanol (MeOH) and to hydrocarbons has garnered significant attention as a strategy to realize a sustainable chemical industry. Analytical targets in CO₂ conversion studies typically include carbon monoxide (CO), hydrocarbons, alcohols, and other reaction products. Selection of appropriate　column and detector combinations must therefore be guided by the nature and concentrations of target analytes. In this application news, we demonstrate simultaneous analysis on two parallel columns by using INJ2-way branch unit to permit detection of CO and hydrocarbons together with alcohols such as MeOH. We also present a simplified measurement approach employing a single-column configuration equipped with a thermal conductivity detector (TCD).
