What is TPO and Why is it Performed?
Discussion on Temperature Programmed Oxidation, how it is performed, and how to study the results using gas analysis.
What is TPR and How is it Performed?
Temperature programmed reduction (TPR) is a material characterization process commonly used in catalysis studies to examine the surface chemistry of metals and metal oxides under varying thermal conditions. TPR-enabled mass spectrometry equipment can acquire quantitative and qualitative data relating to
