This product is designed for in-situ electrochemical Raman and infrared Raman spectroscopy investigations of water-catalyzed materials. It features a dual-chamber H-type cavity with robust sealing performance, enabling electrolyte flow and optional integration with a flow cell. The working electrode is replaceable, and both electrolyte thickness and sample diameter can be adjusted or customized. Equipped with silver/silver chloride and platinum wire electrodes, along with interchangeable components, the device employs optical sapphire or quartz windows to ensure reliable optical access. This configuration is particularly suited for studying catalytic reactions and material behavior under controlled electrochemical conditions in advanced battery and catalysis research.
