La spettrometria di massa con acceleratore … La spettrometria di massa con acceleratore (Accelerator Mass Spectrometry o AMS in inglese) si differenzia dalle altre forme di spettrometria di massa nell'accelerazione ad altissime energie cinetiche del campione prima della sua analisi. Il punto di forza di queste tecnica di spettrometria è la sua capacità di poter separare un isotopo raro da quelli molto più abbondanti nel campione (ad esempio 14C da12C). La tecnologia utilizzata permette di eliminare totalmente molecole isobare, e in molti casi anche di separare nuclei isobari (ad esempio il 14N dal 14C), rendendo possibile la rivelazione di radioisotopi naturali con vita estesa come 10Be, 36Cl, 26Al and 14C. La loro abbondanza isotopica tipica va da 10−12 a 10−18. La tecnica spettrometrica ad accelerazione supera in efficienza tutte le altre tecnologie per la misurazione di isotopi con una vita media estesa .one di isotopi con una vita media estesa .
, Accelerator mass spectrometry (AMS) is a f … 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. This makes possible the detection of naturally occurring, long-lived radio-isotopes such as 10Be, 36Cl, 26Al and 14C. Their typical isotopic abundance ranges from 10−12 to 10−18. AMS can outperform the competing technique of decay counting for all isotopes where the half-life is long enough. Other advantages of AMS include its short measuring time as well as its ability to detect atoms in extremely small samples.o detect atoms in extremely small samples.
, La espectrometría de masas con acelerador … La espectrometría de masas con acelerador (AMS) difiere de otras formas de espectrometría de masas en que acelera los iones hasta energías cinéticas extraordinariamente altas antes del análisis de masas. El punto fuerte del AMS entre los métodos de espectrometría de masas es su poder para separar un isótopo raro dentro de una masa abundante contigua ("sensibilidad a la abundancia", por ejemplo 14C a partir de 12C). El método suprime completamente los isobaros moleculares y en muchos casos puede separar los isobaros atómicos (por ejemplo, 14N de 14C). Esto hace posible la detección de radioisótopos de larga duración, de origen natural, tales como 10Be, 36Cl, 26Al y 14C. Su abundancia isotópica típica varía de 10-12 a 10-18. El AMS puede superar a otras técnicas de conteo de decaimiento radiactivo de todos los isótopos en los que la vida media sea lo suficientemente larga. vida media sea lo suficientemente larga.

Heute wird die Methode für zahlreiche Isotope, üblicherweise langlebige Radionuklide, verwendet.
