inductively-coupled plasma torch

https://doi.org/10.1351/goldbook.08494
Quartz component of an inductively-coupled plasma spectrometer where the plasma is generated and stabilized.
Note:
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.
