Description
The three-electrode electrochemical SPE has a gold working electrode, suitable for a wide range of analytical applications. Each electrode is produced by screen-printing technology and constitutes a circular gold working electrode (2 or 3 mm diameter), a silver pseudo reference electrode, and a gold counter electrode. Additionally, it features a Silver Pseudo-Reference Electrode. The Silver electrode will form a silver chloride layer in a chloride-containing solution, resulting in the popular Ag/AgCl reference system. The enhanced version of this electrode, has a working electrode which received an electrochemical treatment to enhance the surface, i.e. reducing the impedance across the interface.
