Abstract

A mass spectrometry apparatus includes an ion detector and a control circuit coupled to the ion detector. The ion detector includes a pulse counting stage and an analog stage configured to generate a pulse counting signal and an analog signal, respectively, responsive to incident ions. The a control circuit is configured to output the pulse counting signal in a pulse counting output mode and to output the analog signal in an analog output mode. The control circuit is configured to switch from the pulse counting output mode to the analog output mode responsive to the pulse counting signal exceeding a first threshold within a range of about 10 million counts per second to about 200 million counts per second. Related devices and operating methods are also discussed.
