Principle: ICP-MS is a multi-element technique that uses an ICP plasma source to dissociate the sample into its constituent atoms or ions. The ions are extracted from the plasma and passed into the mass spectrometer, where they are separated based on their atomic mass-to-charge ratio by a quadrupole or magnetic sector analyzer and detected by electron multiplier.
