Abstract
Disclosed are a time-of-flight mass spectrometer and signal processing electronics. The signal processing electronics include a plurality of time-to-digital converters configured to receive signal pulses from the same detector anode within the time-of-flight mass spectrometer. The signal processing electronics are further configured to differentiate, and compensate for, those signal pulses caused by the detection of more than one ion. Differentiation and compensation are achieved by using the time-to-digital converters to detect the leading and trailing edges of a signal pulse. The time difference between the detection of the leading edge and detection of the trailing edge is indicative of whether or not the signal pulse was generated by the detection of more than one ion.
