Interferometric mass spectrometry [PDF]
Journal of the American Society for Mass Spectrometry, 2021 Accelerator mass spectrometry (AMS) is a widely-used technique with multiple applications, including geology, molecular biology and archeology. In order to achieve a high dynamic range, AMS requires tandem accelerators and large magnets, which thus confines it to big laboratories.
