Abstract
Method and system of mass spectrometry is provided. The method comprises performing a first and a second MS1 scans on precursor ions produced by ionising a sample. The first MS1 scan comprises mass analysing a first set of the precursor ions transported to a mass analyser using an ion transport device operated at a first setting. The second MS1 scan comprises mass analysing a second set of the precursor ions transported to a mass analyser using the ion transport device operated at a second setting. Energies imparted on the precursor ions by the ion transport device are different in the first and second settings. Based on intensities of mass spectral peaks of the first and second MS1 scans, a mass spectral peak in at least one of the first MS1 scan or the second MS1 scan indicative of a precursor ion mass spectral peak is determined.
