Reference electrodes
• electrochemical measurements (CV, LSV, DPV, etc.)
• electrochemical devices (detectors for HPLC, biosensor, etc.)
Various kinds of them such as aqueous, nonaqueous, calomel
and own-constructing types are available.
• Ag/AgCl type [Aqueous reference electrodes]
• Ag/Ag+ type [Non Aqueous reference electrodes]
• Calomel Standard reference electrode
• Reference electrode for alkaline solution
• Reversible Hydrogen Electrode
∗Keep the reference electrode in a cold dark place.
