Working electrodes for Flow cell

Working electrodes for Flow cell

Our working electrodes for flow cell are mounted in blocks of PEEK. This resin protects the electrodes from external noise and allows researchers to utilize them regardless the content of mobile phase of HPLC because of their hardness and organic slovent-resistance. Glassy carbon is usually chosen for the redox reaction study on liquid chromatography. Platinum, Gold, Carbon paste and Nickel electrodes are utilized for special purporses.

 

  • Excellent chemical resistance
  • Easy maintenance of the working electrode
  • Working electrode can be polished with PK-3 Polishing kit
 

Application of Electrodes

  • GC: commonly used for measurement of Redox behavior
  • PFC: commonly used for measurement of Redox behavior
  • Au: measurement of thiol-related compounds with amalgamate electrode
  • Pt: measurement of hydrogen peroxide and oxidized substance
  • Ag: measurement of cyano-sulfide
  • CP: derivatizationed electrode by filling compound of carbon paste, enzyme and chemical substances into it
  • Ni: amino acids measurement by chemical derivatization

Structure of the working electrode

FC_CrossFlow.jpg

The dual glassy carbon electrode is considered to be a standard working electrode for cross flow cell. It is composed for two glassy carbon electrodes, of the 3 mm placed in series. Also it coul be rotated 90 degrees and applied as a parallel mode. The selectivity improves with the application of dual series electrode. In the parallel mode, identification of the substance, from the different applied voltage response ratio, is possible.

Jumper connector for dual electrodes

For the dual electrode, the electrode surface area doubles by using the jumper connector (002245), and high sensitivity analysis becomes possible. For the working electrode, the platinum/gold electrode and others .
