Basic electrochemical H-cell setup (redox.me)

This is a stationary solution double compartment electrochemical H-Cell for measurements of electrodes in a form of:

a) rod/disc (6 mm dia.),

b) thin film deposited on a flat substrate (using a wire clip) and

c) membrane (using a wire clip).

 

The working, counter and reference electrodes are mounted in a top casing either in 2-, or 3-electrode setup. The counter electrode is placed in a compartment separated from the other electrodes by ion-exchange membrane (19 mm to 25 mm dia.), so the electrochemical products appearing at working and counter electrode do not affect the opposite electrode. The counter electrode compartment is equipped with a separate inlet and outlet for easy filling with an electrolyte and evacuation of gaseous products. It can accommodate standard Metal Wire Auxiliary Electrode as well as square shape electrodes with sizes up to 25 mm x 25 mm. The cell elements are constructed with materials that are inert to the sample (glass and PEEK). It well fits aqueous (FKM/EPDM 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. After removal of the counter electrode glass compartment, the cell gets the functionality of a Basic Electrochemical Cell – BEC 50 mL. 

The cell chamber is available in several material variants here.

 

Application note:
The reference electrode tip and working disk electrode tip should be placed in the middle of the membrane. This will ensure a low potential drop throughout the electrolyte solution for low-current experiment. Various auxiliary electrodes are suitable for this cell including metal wire and metal foil/mesh/foam electrodes as well as graphite rod. The bubbling of gas through the solution must be stopped prior to experiment.

  • SIRE Sensor Cell Set (Sensor with Injectable Recognition Element)

    The SIRE Sensor Cell Set consists of a sensor with an integrated non-removable specialised chamber.

     

    The set also contains a syringe which will allow the injection of the recognition element (Enzyme).
    The SIRE Sensor Cell uses the concept of soluble enzymes into a reaction chamber separated from the sample by a semi permeable dialysis membrane. The analyte (for example maltose), enters into the reaction chamber by diffusion. The analyte reacts with the recognition enzymes creating H2O2 which is oxidized on a screen printed Pt electrode. The current corresponds to the amount of analyte.

  • 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.
