09098 IUPAC Gold Book - solid amalgam electrode 10.1351/goldbook.09098 09098 current initialism: SAE 1 Electrode made of a solid amalgam of an appropriate metal. Solid amalgam electrodes are electrochemically similar to the hanging mercury drop electrode. Their main advantages are high hydrogen overpotential (similar to liquid mercury); a wide working potential range; the simple mechanical, chemical, and electrochemical regeneration of the surface; a long lifetime; low toxicity of material (comparable with that of dental amalgams); applicability for field measurements; compatibility with flow-through systems; simple construction, without mobile parts; and easy miniaturization. Liquid and paste amalgams can also be used.
