This study presents a fast and precise solvent characterizing method for the screening of novel CO2 capture systems. In this method, time-base Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy was used for in-situ monitoring of CO2 absorption and desorption processes of non-aqueous amine systems. Different equal mole amines were used to qualify and quantify changes of the IR vibrations. The method enables identification of reaction mechanism along with full speciation. In order to confirm repeatability and representability of the screening test, a replication experiment using liquid-flow cell FTIR analysis is also presented.
