The TPO process involves several steps: 1. Sample Preparation: The sample, typically a catalyst, is placed in a reactor. 2. Temperature Ramp: The temperature is gradually increased at a controlled rate while an oxidizing gas, often a mixture of oxygen and an inert gas like helium, flows over the sample. 3. Detection: The effluent gases are analyzed using detectors such as mass spectrometers or infrared spectroscopy to identify and quantify the gases evolved during oxidation. 4. Data Analysis: The resulting data, usually presented as a plot of gas concentration versus temperature, helps in identifying the temperatures at which different oxidation events occur.
