The argon plasma used in ICP-OES is contained in the ICP-OES torch and generated by radio-frequency (RF) energy which passes through the RF coil. The ICP-OES torch consists of a quartz outer tube set and either a quartz or alumina injector.

Agilent's ICP-OES torches, RF coils, and accessories are designed to extend the capabilities of the instrument while providing optimized performance and ease of use.
