High-Sensitivity Analysis of Formic Acid in Methanol Solution Using Jetanizer^™

User Benefits

- Using Jetanizer as a GC-FID nozzle makes it possible to accurately analyze formic acid in methanol solution. - The Jetanizer simply replaces the conventional GC-FID nozzle, making it easy to install and inexpensive.

Introduction

Green Transformation (GX) initiatives aim to transition from fossil fuels to green energy and balance greenhouse gas emissions reduction with economic growth. These initiatives are expected to use innovative technologies such as artificial photosynthesis, which utilizes sunlight to produce hydrogen and organic compounds from water and carbon dioxide. Research on such artificial photosynthesis, along with the analysis of impurities in chemical products and raw materials, highlights the demand for high-sensitivity analysis of formic acid. A simple method for analyzing formic acid is gas chromatography (GC), where a TCD detector is used for high-concentration samples, and a BID detector is used for low-concentration samples. Unfortunately, the FID detector, a general-purpose detector, lacks sensitivity to formic acid. However, by replacing the FID detector with a Jetanizer (In-Jet type methanizer) that contains a catalyst in the FID nozzle and adjusting the analysis conditions, high-sensitivity measurement of formic acid at the ppm level becomes possible. This Application News presents an example of the high-sensitivity analysis of formic acid contained in a methanol solvent using Jetanizer as the GC-FID nozzle.
