1. VeeMAX III, can be used horizontally and vertically, and must be designed to be compatible with the JASCO FT/IR-6X infrared spectrometer. 2. A H-type split electrolytic cell that is designed to be compatible with VeeMAX III for in situ FTIR measurement. The specifications of cell structure: a) H-type split electrolytic cell with main and side compartments; b) The electrolytic cell should have both an air inlet and an air outlet; c) Volume of working electrode chamber should be at least 15 ml to reduce test errors caused by solution evaporation. 3. Airflow ports: The electrolytic cell should have both an air inlet and an air outlet. 4. Crystal material: Silicon (Si), 60°. 5. Electrode materials that fit with the H-cell: Platinum counter electrode and Ag/AgCl reference electrode, sized to fit the electrolytic cell. 6. 1-Year Warranty Included.
