Abstract
A mass spectrometer comprises an ion detector, an analog-to-digital (A/D) converter, a sample adjuster, and an adder. The A/D converter is configured to generate digital samples representing an analog signal received from the ion detector during a mass scan. The adder is configured to sum the samples with corresponding unsuppressed samples representing analog signals received from the ion detector during previous mass scans, the summed samples defining a mass spectrum. The sample adjuster is configured to identify a peak defined by the samples and to suppress all but one of the samples defining the identified peak to enhance resolution of a peak in the mass spectrum.
