Introduction

In recent years, as part of efforts to achieve carbon neutrality, research on gas synthesis using CO₂ has been actively conducted. For energy-efficient gas synthesis, the selection of novel reaction systems using catalysts is crucial. Qualitative and quantitative analysis of gases generated in catalytic reaction systems serves as an important indicator for evaluating these systems.
In this paper, three types of instruments capable of quantitative and qualitative gas analysis were used to measure standard gases, including H₂, CO, CO₂, and CH₄, which are often the targets in catalytic reactions using CO₂. The instruments used were a gas chromatograph(GC), a Fourier transform infrared spectrophotometer(FTIR), and a transportable gas analyzer(CGT). The characteristics of each model are introduced along with the measurement results of the standard gases.
