Flow Cell

Working Electrodes for Flow Cell

Our Working electrodes for flow cell are mounted on 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 hard, organic solvent-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 purposes.

Features
• Become stable immediately
• Usable with acid, alkaline, and organic solvents
• Easy maintenance of Working electrodes by wipe with acetone
• Working electrodes can be refreshed using PK-3 cell Polishing Kit
• Can be used as chemically modified electrodes or bio-sensors



Cross Flow Cell

Radial Flow Cell

Radial Flow Cell is developed for microbore chromatography. Its detecting efficiency will improve when flow rate is 10 µL/min or lower. This flow cell consists of thin layer electrode and symmetric design.

Flow schematic diagram for Radial flow cell





The wall jet of the sample, after hit in to the electrode's surface, spreads in three dimensions. After hitting the sample on a thin layer electrode directly, it flows to the perimeter from the center of the radiated electrode, improving the sensitivity.

Flow Cell - 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, and high sensitivity analysis becomes possible. For the working electrode, the platinum/golg electrode and others are also available.






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
