Reference electrode selection

The reference of the potential in electrochemical measurement is based on the reference electrode, so it is a very important electrode.
BAS Inc. has a wide line of reference electrodes, as reference electrode for measurement in aqueous solution, non-aqueous solution, alkaline solution, and reversible hydrogen electrode. Also, the reference electrode has the standard size, which makes possible to fit in all of our accessories.
Furthermore, to complete the line up, we have the screw type, which could be used in our Cross flow cell, Radial flow cell, EQCM flow cell and SEC-Spectroelectrochemical flow cell.

Below, two quick tools for selecting an appropriate reference electrode for your measured sample are introduced.

• Reference electrode selection by pH of the sample
• Reference electrode selection using flowchart

pH of the sample

The pH of the sample has a major influence on electrochemical measurements, as it directly affects reaction kinetics, thermodynamics, and the state of the electrode surface. It also limits the use of certain reference electrodes, such as glass-based electrodes, in alkaline solutions.
