The execution of in situ and operando MS involves sophisticated setups that often require specialized instruments and reactors. Here are the general steps:
Reactor Design: The reactor must be designed to accommodate MS analysis without disrupting the reaction conditions. This often involves the use of custom-built cells and windows for spectroscopic access. Mass Spectrometer Integration: The reactor is connected to a mass spectrometer capable of detecting and analyzing various species in the gas or liquid phase. Data Collection: The mass spectrometer collects data in real-time, often in conjunction with other analytical techniques like X-ray absorption spectroscopy or infrared spectroscopy, to provide a comprehensive view of the catalytic process. Data Analysis: The collected data is analyzed to identify the species present, their concentrations, and how these change over time, providing insights into the reaction mechanism and catalyst performance.
