FTIR spectroscopy is a powerful tool for analysis of HCl at subppm levels. FTIR is highly sensitive to H 2 O and CO 2 thus in order to minimize the environment effect and ensure the stability of TG-FTIR the whole system was purged by nitrogen before and after each experiment.
The sample cell is placed in the sample chamber of the spectrometer and a spectrum is recorded at the highest possible resolution.
