Inductively coupled plasma (ICP) is a technique for high-temperature vaporization and excitation of samples for instrumental analytical chemistry. It is especially popular for generating samples for atomic emission spectrometry (AES) and mass spectrometry.[1]
The convenience of ICP for AES has led AES to displace neutron activation analysis in a number of applications, since NAA historically has needed a non-portable nuclear reactor.
Heat source
The ICP uses radiofrequency-(RF, 27.12 MHz, 40 MHz) induced plasma generated by an induction coil that produces a magnetic field (H). For typical laboratory uses, the power requirement is between 1 and 5 kilowatts.[2]
