Published in 2023 at "Analytical chemistry"

DOI: 10.1021/acs.analchem.2c05243

Abstract: In time-of-flight mass spectrometry (TOFMS), ion detection is often achieved via electron multiplication followed by fast analog-to-digital conversion (ADC). This detection approach is chosen over time-to-digital conversion because it extends the dynamic range of TOFMS… read more here.
