Cross Flow Cell

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. Thin Layer Cell has been used as a electrode for research such as flow injection analysis (FIA) and the HPLC.
 

Note: Working electrode, reference electrode and gasket are sold separately.

Cross Flow Cell Structure

Cross Flow Cell is capable of quantitation at the level of 10-15 mol by the flow rate: 1 mL/min - 100 µL/min.

• Detection electrode for HPLC
• Electrode for flow injection
• Electrode for bio-sensor development

Structure of the working electrode

 

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.
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/gold electrode and others are also available.
