Carbon is commonly added to sulfate‐fined silicate‐glass batches to enhance the fining process. Reactions between carbon and Na 2 SO 4 modify the SO x emissions from Na 2 SO 4 decomposition. Fourier‐transform infrared (FTIR) spectrometry is used to analyze the emission of air pollutants from the isothermal decomposition of Na 2 SO 4 + C undertaken using thermogravimetric analysis (TGA). The FTIR spectrometer is calibrated using standard gas mixtures containing CO, CO 2 , SO 2 , NO, and NO 2 . The collected spectra are quantified using the classical least‐squares (CLS) approximation. The TGA‐FTIR system provides SO x , and CO x , concentrations versus time data from the isothermal decomposition of Na 2 SO 4 , in the presence of a carbon black. Mass spectrometry (MS) complements FTIR by being able to detect SO( g ).
