Abstract
A highly sensitive spectrometer system having inherently low backgrounds is described. In this new molecular accelerator mass spectrometry procedure, negative molecules containing the isotope of interest are accelerated using a tandem accelerator. Subsequent electron stripping and analysis stages outside of the accelerator fragment the molecules and eliminate mass upon charge ambiguities. The combination results in a cost effective accelerator mass spectrometer with high sensitivity and low backgrounds.
