accelerator mass spectrometry

A specialised form of mass spectrometry used for low-level analysis of 14C isotopes in radiocarbon dating and biological tracer studies, in which atomic ions are formed from the sample by charge-stripping in a very high-voltage source, typically coupled to a Van de Graff accelerator.
