Description

technical field [0001] The invention relates to an in-situ electrochemical-Raman spectrum measurement system in a high-temperature and high-pressure water fluid environment, belonging to the technical field of Raman and three-electrode electrochemical measurement. Background technique [0002] Electrochemical measurement technology is one of the few in-situ research methods that can be applied in high-temperature and high-pressure water fluid environments. It uses electrical signals as excitation and detection methods to obtain relevant electrode / electrolyte solutions by measuring current, potential and charge. The structure of the interface, the mechanism and kinetic properties of the electrode process. Due to its high sensitivity, changes in molecular layers occurring at electrochemical interfaces can be detected. However, the traditional electrochemical method has certain limitations. For example, it does not have the ability to characterize specific molecules, and canno...
