  Membrane Capacitive Deionization configurable cell (redox.me)

  Membrane Capacitive Deionization (MCDI) configurable cell has been designed to conduct research on removal of charged ionic species from aqueous or organic solutions (i.e., Desalination/Demineralization) via electrostatic (i.e., non-Faradaic) or electrochemical (redox) interactions. The MCDI cell contains two graphite current collectors that can serve as polarization electrodes. However, if the electrode material is the subject of research, it should be applied to an additional current collector, such as graphite paper or metal felt (not included in the product). Different electrode materials can be installed on both sides of the cell. If the thickness of these electrodes exceeds 250 micrometers, different gaskets are required. In such a case, please contact us for a solution.

  The cell is designed in such a way that replacing the electrodes does not require removing the membranes or flow fields. It is enough to unscrew the plungers on both sides and replace the electrodes. In the standard configuration, the liquid in the main channel and side channels flows through the flow field cut from PEEK. However, these can be replaced with a porous material such as felt or a battery spacer, which will allow fluid flow. If work with materials of dimensions different from those listed in the specification is required, we can supply seals of different thicknesses or customize the cell. The cell allows for the installation of one or two ion-exchange membranes (not included in the setup). Their thickness is not critical, and it is not necessary to adjust the thickness of the membrane gaskets pressing them. The cell elements are constructed with inert materials to the sample (PEEK). It well fits aqueous (FKM gaskets and O-rings) and organic solvent (FFKM gaskets and O-rings) electrolyte requirements. The construction of the cell is gas-tight.

   

  Application note:
  MCDI cell can be configured to allow the following cell architectures:

  1. Flow-by CDI consisting of: (i) two porous carbon or metal based current collectors coated with capacitive (e. non-Faradaic) material, and (ii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields and membranes are not installed.  
  2. Membrane CDI consisting of: (i) two porous carbon or metal based current collectors coated with capacitive (e. non-Faradaic) material, (ii) two ion-exchange membranes (cation exchange membrane and anion exchange membrane) separating electrodes from the main flow field, and (iii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields are typically not installed. However, there are cases where installing both side flow fields is justified. All the graphics included in the product page refer to that configuration.
  3. Inverted CDI consisting of: (i) two porous carbon or metal based current collectors coated with capacitive (e. non-Faradaic) material where anode is treated for net negative surface charge and a cathode is treated for net positive surface charge, and (ii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields and membranes are not installed.  
  4. Flow-electrode CDI consisting of: (i) two porous carbon or metal based current collectors with flowing electrodes made of capacitive (e. non-Faradaic) carbon suspension, (ii) two ion-exchange membranes (cation exchange membrane and anion exchange membrane) separating electrodes from the flow chamber, (iii) a main flow field enabling the feed water to be transported between electrodes, and (iv) two side flow fields for liquid electrodes. All the graphics included in the product page refer to that configuration.
  5. Hybrid CDI consisting of: (i) a Faradaic (e. battery) electrode for cation adsorption/desorption, (ii) a capacitive (i.e. non-Faradaic) electrode for anion adsorption/desorption, (iii) an anion exchange membrane placed adjacent to the capacitive electrode, and (iv) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields and a cation-exchange membrane are not installed.  
  6. Cation intercalation desalination consisting of: (i) two porous carbon or metal based current collectors coated with Faradaic cation intercalation materials, (ii) an anion exchange membrane separating electrodes, and (iii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, one side flow field and cation-exchange membrane are not installed.  
  7. Desalination battery consisting of: (i) two porous carbon or metal based current collectors coated with redox (e. Faradaic) material (one for cation adsorption/desorption and the other for anion adsorption/desorption), and (ii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields and membranes are not installed.

  EmStat4 MUX (2-in-1: Potentiostat with integrated multiplexer)

  Gone are the days with too many cables. With the EmStat4 MUX you have a potentiostat and a multiplexer in one! The EmStat4 MUX is a powerful potentiostat, galvanostat and impedance analyzer and supports all popular electrochemical techniques. Its 8 channels allow for sequential measurements, for example eight Screen-printed electrodes, or eight working electrodes in eight different  cells.  The instrument’s measurements can be highly customized using MethodSCRIPT. The 4 different cell connections available allow for many different setups. When the measurements are finished, you can easily save your results in PSTrace, or export your results to Excel. 

   

  More information could be found tought link:

  https://www.palmsens.com/product/emstat4-mux/

   

  • Integrated 8-channel multiplexer
  • Supports 2-, 3- and 4-electrode setup using Sense Lead
  • Potential range: ± 3V 
  • Compliance voltage: ± 5V
  • Current ranges:  1 nA – 10 mA
  • Maximum current: ± 30 mA
  • FRA / EIS up to 200 kHz

  Two modes of operation

  • Consecutive mode: this mode switches channel when a complete measurement has finished
  • Alternate mode: this mode switches all activated channels within the specified time interval of a measurement.

  In both modes the unselected Working Electrodes can either be left floating or switched to Ground to keep the specified voltage.

  Supports a 2-, 3- or 4-electrode setup

  • Connect four electrodes per channel by using the Sense Leads. 
  • Or connect only three electrodes per channel by internally connecting all Sense electrodes to the Working Electodes in software.
  • Do you need to connect only two electrodes per channel? Combine the reference and counter electrode physically on the cable, or with a single click on the PSTrace software.

  

  8 to 128 channels

  Is 8 channels not enough? If more channels are required, one or more MUX-R2 can be stacked to the EmStat4 MUX for a total of up to 128 channels.

  Script your experiments!

  Via the script window of PSTrace it is possible to perform a different experiment on each of the channels sequentially. Alternatively, you can use MethodSCRIPT to fully customize your measurements per channel.

  Multichannel or Multiplexer?

  To make it easier for you to decide, if  a multiplexer or a multichannel device is more suitable for your application, we have created a short explanation of multiplexers and multichannels.

  EmStat4T (Tailored electrochemistry through touch-controlled apps)

  The EmStat4T is a programmable handheld potentiostat with a touchscreen, which is ideal for sensor research and sensor-based applications. It offers two main modes of operation:

   

  1. Remote Control: where it functions as a conventional potentiostat, controlled directly by our PSTrace software for Windows or PStouch app for Android. These applications allow you to run measurements, view results, and perform data analysis.

   

  1. Standalone: where the instrument is controlled via its touch interface to run a wizard‑style app for electrochemical analysis. Compose custom apps easily using the Visual MethodSCRIPT Editor included in PSTrace for Windows. Apps eliminate the need for a computer, tablet, or smartphone. This makes the EmStat4T an ideal solution for point-of-care applications and field research such as environmental analysis or corrosion monitoring.
