Figure 1:
CO₂ evolution (normalized MS signals expressed as reaction progress ) during the decomposition of an inorganic pigment under isothermal conditions. The values of the temperature in °C are marked on the curves. Isothermal experiment should be carried out at temperatures below 250 °C to avoid the occurrence of the temperature settling problem.
 

Figure 2:
Comparison between TG, MS-H₂O (Gas 1) and MS-CO₂ (Gas 2) (expressed as reaction progress , normalized signals) of an inorganic pigment under isothermal conditions (250°C).
