Abstract: A scan of a separating sample mixture is received from a mass spectrometer at each interval of a plurality of intervals. It is determined at a first interval that a received mass spectrometry scan at the first interval and one or more preceding received mass spectrometry scans include a varying ion signal that represents an ion of a known compound and has an intensity above a threshold level. The mass spectrometer is instructed to perform a dependent scan for the ion at the first interval producing a spectrum for the known compound. A second interval is selected after the first interval where the varying ion signal has an intensity that is not above the threshold level. The mass spectrometer is instructed to perform a dependent scan for the ion at the second interval producing a spectrum for a background.
