Precise ion mass determination method for time-of-flight mass spectrometer e.g. for biochemistry, with pulser for pulsing ions in synchronism with measuring cycle of measuring device for detector current

摘要

The mass spectrometer has a pulser (12), an ion detector (14) and a measuring device for the ion current at the detector, the ions pulsed via the pulser in synchronism with the measuring cycle of the measuring device, allowing a measured ion current signal to be assigned to a preceding pulsing of the ions, for precise measurement of the time-of-flight and specific mass of the ions.
