Inductively coupled plasma (ICP) techniques
An argon plasma torch
An ICP is an excitation source in which power is generated through electromagnetic induction to produce an electrodeless discharge in a gas - usually argon.
The plasma is generated inside and at the open end of an assembly of quartz tubes known as the torch.
Typically, liquid samples are aspirated in a stream of argon gas and carried to the plasma torch. Temperatures here can range from 6,000K to 10,000K - enough to break down most molecular and ionic bonds and comparable to the surface of the sun.
The subsequent separation and analysis of the resulting ions differs depending on the technique used.

Inductively coupled plasma atomic emission spectroscopy (ICP-AES)
Find out about ICP-AES. In this method, electromagnetic radiation emitted by excited atoms is analysed by a spectrometer. It is routinely used to analyse digests of rocks, minerals, organic materials and waters.

Inductively coupled plasma mass spectrometry (ICP-MS)
Learn about ICP-MS, which separates and detects ions based on their mass-to-charge ratio. It is used in a variety of applications and the excellent sensitivity of the instrument means that analysis of rare earth elements can be particularly good.
