ALS Non-aqueous (Ag/Ag+) reference electrodes
ALS Non-aqueous (Ag/Ag+) reference electrodes
Non-aqueous reference electrodes are used for electrochemical measurements in anhydrous, organic electrolytes.Reference electrodes are required for virtually all types of electrochemical measurements. In addition to a range of electrodes for aqueous electrolytes, ALS also offers electrodes for organic media and a reversible hydrogen electrode (RHE).
Product Description
A silver wire and silver ions are used as a half-cell system in non-aqueous reference electrodes. Different solvents can be used as organic solvents. However, care must be taken to ensure that their potential window is sufficient for the intended measurements and that both a silver salt and a conducting salt can be dissolved well enough in them. In addition, the solvent and the conducting salt itself should of course not undergo an electrochemical reaction.
Typical conducting salts are, for example, tetraethylammonium perchlorate (TEAP) or tetrabutylammonium hexafluorophosphate (TBAP). The electrodes are supplied with 3 ml TBAP in acetonitrile for filling.
