Short summary
We show results from a new type of ion detector technology for mass spectrometry that allows us to measure ion beams more precisely. This technology expands the range of ages we can measure using a single instrument and makes it possible to measure those ages – including all required corrections and adjustments – with more confidence. We show measurements of widely used standard materials for Ar / Ar, including air and synthetic standard gas, to illustrate the capabilities of the new detectors.
