This ATR-FTIR BM 15 mL EC (Attenuated Total Reflectance Fourier Transform Infrared Bottom Mounted Electrochemical) cell has been designed for the VeeMAX III device from PIKE Technologies. This advanced cell seamlessly integrates ATR-FTIR analysis and electrochemical measurements, offering real-time insights into reaction kinetics, intermediate species, and reaction mechanisms. The cell enables surface analysis of electrode materials, investigation of electrode surfaces' chemical composition and structure, surface functional groups and adsorbed species, as well as the composition, stability and chemical reactions of electrolyte solutions during electrochemical processes. In this configuration, the cell is compatible with both 60 deg and 45 deg crystals. The sample exposed area is about 1.5 cm2 (14 mm dia.) and the maximum electrolyte volume is 15 mL. The cell lid securely mounts 6 mm dia. counter and reference electrodes, facilitating 2-electrode and 3-electrode setups. An optional adapter is available for 20 mm diameter flat window/crystal compatibility. Cell elements are constructed from materials inert to the sample environment (PEEK, Fluoropolymers), and either aqueous (FKM) or organic solvent (FFKM) compatible O-rings can be installed to meet electrolyte requirements. The construction is gas-tight.

Application note The ATR-FTIR BM 15 mL EC cell, in conjunction with the VeeMAX III device, enables in-depth analysis of changes in interfacial mass and physical properties during electron transfer processes. It is recommended to place the reference electrode tip close (3-5 mm) to the crystal surface to minimise potential drops throughout the electrolyte solution. The cell supports a range of auxiliary electrodes, including metal wire, metal foil electrodes and graphite rods.
