Operando MS involves integrating a mass spectrometer with a catalytic reactor. The setup typically includes a reaction chamber where the catalyst is placed and a gas inlet and outlet system to introduce reactants and remove products. As the catalytic reaction proceeds, the effluent gases are continuously sampled and analyzed by the mass spectrometer. This allows for the detection of various species, including reactants, intermediates, and products, providing a comprehensive picture of the catalytic process.
