Preferred term
accelerator mass spectrometry
Definition
- Accelerator mass spectrometry (AMS) is a form of mass spectrometry that accelerates ions to extraordinarily high kinetic energies before mass analysis. The special strength of AMS among the mass spectrometric methods is its power to separate a rare isotope from an abundant neighboring mass ("abundance sensitivity", e.g. 14C from 12C). The method suppresses molecular isobars completely and in many cases can separate atomic isobars (e.g. 14N from 14C) also. Other advantages of AMS include its short measuring time as well as its ability to detect atoms in extremely small samples. (Adapted from: https://en.wikipedia.org/wiki/Accelerator_mass_spectrometry)
