Harmonic generation spectroelectrochemical cell (HGSEC) in situ.

This product is designed for in situ harmonic generation spectroelectrochemical studies, integrating a three-electrode configuration within a compact optical cell. It features a platinum disc working electrode (φ5 mm), a platinum wire counter electrode, and a silver/silver chloride reference electrode, together with a calcium fluoride optical window for broadband UV-to-IR transmission. The combination of the transparent window and standard electrode geometry enables simultaneous electrochemical control and nonlinear optical signal acquisition, making it particularly suitable for probing interfacial processes in energy materials, catalysis, and electrochromic systems. Its construction supports real-time monitoring of charge transfer and surface reactions under applied potential, offering a reliable platform for researchers investigating structure–property relationships at electrode–electrolyte interfaces.
