08494 IUPAC Gold Book - inductively-coupled plasma torch 10.1351/goldbook.08494 08494 current 1 Quartz component of an inductively-coupled plasma spectrometer where the plasma is generated and stabilized. In ICP the torch is an open three concentric tubes assembly allowing the introduction of the three gas streams constituting the plasma. The inner tube of the torch can be made of a different material such as alumina and is usually called the injector. inductively-coupled plasma spectrometer https://goldbook.iupac.org/terms/view/08489 PAC, 2021, 93, 647.
