	Inductively coupled plasma - Wikipedia, the free encyclopedia
		An inductively coupled plasma (ICP) is a type of plasma source in which the energy is supplied by electrical currents which are produced by electromagnetic induction, that is, by time-varying magnetic fields.
		Another benefit of ICP discharges is that they are relatively free of contamination because the electrodes are completely outside the reaction chamber.
		In a capacitively coupled plasma (CCP), in contrast, the electrodes are placed inside the reactor and are thus exposed to the plasma and subsequent reactive chemical species.

	ICP-MS - Wikipedia, the free encyclopedia
		It is based on coupling together an inductively coupled plasma as a method of producing ions (ionization) with a mass spectrometer as a method of identifying and detecting the ions.
		ICP (Inductively Coupled Plasma) - this is a high temperature plasma (partly ionised argon) sustained with a radiofrequency electric current, which acts to produce ions.
		MS (Mass Spectrometry) the ions from the plasma are extracted through a series of cones into a mass spectrometer, usually a quadrupole.

		Within the center of this coil is a quartz plasma torch where the plasma is initially formed from the seeding the of argon gas with a spark from a Telsa unit (a device similar to a spark plug).
		These concentrations of electrons in the plasma reach equilibrium very quickly, after which the plasma will remain “lit” as long as the RF field in maintained and a constant supply of argon gas is injected into the plasma.
		The plasma torch is designed in such a manner that the sample is then injected directly into the heart of the plasma.

	Inductively Coupled Plasma Emission
		Inductively Coupled Plasma Emission - Mass Spectrometry (Laser Ablation) A general description of the method.
