Abstract
A system and method of processing signals generated at a detector of a mass spectrometer prior to signal conversion in which a pre-ADC offset is applied to the signals that is adjustable in polarity and magnitude in accordance with a user-selected mode. According to a first mode, a positive offset is applied to the signals to improve quantitation accuracy and in a second mode, a negative offset is applied to the signals to improve resolution and mass assignment.
