  Spectro-electrochemical flow cell setup (redox.me)

  This is a horizontally mounted, multi-purpose spectroelectrochemical cell designed to be used with standard UV-Vis or IR spectrometers. It enables obtaining electrochemical and spectroscopic information from liquid sample or thin films in systems where variations in applied potential induce changes in observed spectra. It consists of a polyether ether ketone (PEEK) flow chamber equipped with a magnetic or screw mount sample holder, screw mount quartz window holder and two different mini tripods. It well fits aqueous (FKM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements.

  The cell is meant to be used with a standard reference electrode having 6 mm in diameter and a counter electrode either in the form of a rod or helix with 6 mm in diameter and 15 mm active length.

   

  Application note:
  The spectroelectrochemical cell is used to study the relation between absorbance/transmittance and electrochemical potential. It enables real-time monitoring of optical change in electrochromic materials. It also enables in-situ spectral acquisition for detection, identification and characterization of short-lived electrochemically-generated species/intermediates, resulting in a detailed investigation of the mechanistic pathways of redox processes.

  Bottom mount front contact electrochemical cell setup (redox.me)

  This is a static voltammetry cell with variants for different sample dimensions. The sample is loaded from the bottom via magnetic or screw mount, while counter or/and reference electrodes are mounted in the lid as either 2-, or 3-electrode configuration. The cell is constructed with materials that are inert to the sample environment (glass and PEEK), and it can be used with FKM/EPDM O-rings or FFKM O-rings for aqueous or organic electrolyte requirements, respectively. The construction is gas-tight and inert gas can be bubbled through the electrolyte to remove and exclude contaminants such as air or water.

   

  Application note:
  The reference electrode tip should be placed close to the sample surface to ensure a negligible potential drop throughout the electrolyte solution during low-current experiments. In the magnetic variant of the cell, the strength with which the magnets hold the sample is adjusted by adding or removing the washers under the magnets. Thanks to this procedure, the distance between the magnets changes, with it, the force of their attraction. Various auxiliary electrodes are suitable for this cell, including metal wire and metal plate electrodes as well as carbon-based electrodes (graphite or Glassy Carbon). If a purge gas is used, stop the flow during experiments for better results. 

   

  Specification:
  nominal exposure area: 0.07 cm² for 5x5mm², 0.2 cm² for 7x7mm², 0.5 cm² for 10x10mm², and 1.33 cm² for 15x15mm²
  minimum electrolyte volume: 2.5 mL
  maximum electrolyte volume: 15 mL
  electrode plug diameter: 6 mm
  substrate size: 5x5mm², 7x7mm², 10x10mm², and 15x15mm², other sizes available on request
  minimum substrate thickness: 0.4 mm*

  *lower thicknesses are also feasible when using a pad below the sample

  Raman Electrochemical Flow Cell, active area: 3.5 cm2, volume: 4.5 mL (redox.me)

  This cell combines two classical analytical techniques such as electrochemistry and Raman spectroscopy, to obtain in-situ chemical information about the reactions taking place during an electrochemical experiment. It consists mainly of three elements: (i) sample holder with Tantalum (formerly Copper) foil serving as an electric contact to working electrode surface, (ii) chamber in which reference and counter electrodes are installed together with electrolyte inlet and outlet and (iii) lid which seals the cell and holds the Sapphire window. The sample consisting of a thin film of electrochemically active material deposited on a rigid or flexible substrate (working electrode) is loaded from the bottom via magnetic or screw mount. The counter or/and reference electrodes are mounted in a top casing (either 2-, or 3-electrode setup. The oval counter electrode made of e.g. Platinum wire assures uniform distribution of the field lines along the path to working electrode. During an experiment Raman laser is focused onto the surface of a thin film working electrode through a transparent Sapphire window and thin layer of electrolyte (total optical path of 3.25 mm). The electrolyte thickness of 2.25 mm ensures free diffusion of ions (e.g. protons) and its counter ions.

   

  The electrode adapter for installing 6 mm dia. electrodes inside Raman ECFC is available here. It enables using disk electrode, plug with clip or any other rod-shape electrode (e.g. graphite rod) or current collector (e.g. metal mesh, graphite coated metal mesh, metal foil, graphite coated metal foil, metal foam, carbon woven and non-woven fabrics, carbon paper, etc.) as working electrode instead of a flat electrode in default Raman ECFC configuration. 

   

  The screw mount variant of Raman ECFC can be converted into GDE Raman ECFC by using Gas Compartment. This conversion allows installation of Gas Diffusion Electrodes as working electrode. 

   

  The cell elements are constructed with materials that are inert to the sample (PEEK, Fluorocarbons). It well fits aqueous (FKM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight and can be used when the removal and exclusion of contaminants such as oxygen and water is required by bubbling of an inert gas through the electrolyte (in an external reservoir).

   

  Application note:
  This cell can be used to track kinetic phenomena such as the near-surface proton concentration changes during oxidation and reduction reaction at working electrode. It can be also used to identify materials such as carbon, metal oxides, polymers and electrolytes, and to determine their structure and distribution. Various metals are suitable for this cell as auxiliary electrode including Platinum, Gold and Silver.
