ICP-MS (Inductively Coupled Plasma – Mass Spectroscopy)

ICP-MS – (Inductively Coupled Plasma – Mass Spectroscopy) Analytical technique used to identify and quantify elements in a solution, typically of relatively low (usually parts per billion to parts per quadrillion range) concentration elements.

• Argon gas interacts with and ionizes elements in a test sample – the mass spectrometer inside the instrument separates these ions by mass to charge ratio to determine ion identity and counts number of these ions detected per second (CPS) to determine identity and concentration (by comparing to a standard) of analytes present.
