| Application: | Platinum wire finds major applications as an electrode, such as: • Auxiliary electrode in flow cell to determine ammonia content. • Electrodes for photoconductive stimulation of neurons cultured on silicon wafers. • Electrode to give current flow in electrophoresis chamber for ion migration. Additionally, Pt wire may be used: • As a microelectrode-indicator electrode in voltammetry. • As a transvascular embolic agent. • To study chronopotentiometry of hydrogen peroxide with a platinum wire electrode or • In gas detection instruments. |
| General description: | Platinum (Pt) is a highly ductile, malleable and unreactive metal. It is resistant to corrosion and stable at high temperatures. Although resistant to hydrochloric and nitric acid, it dissolves readily in hot aqua regia to form chloroplatinic acid. |
