Abstract
A method of mass spectrometry is provided. The method comprises eluting a sample from a chromatography system, and calculating a desired maximum scan duration for the sample eluting from the chromatographic system based on a duration of a chromatographic peak of the sample as it elutes from the chromatography system, and a minimum number of scans per chromatographic peak to be performed. A maximum accumulation duration is calculated based on the desired maximum scan duration. The sample is ionised to produce sample ions using an ion source. The sample ions are directed along an ion path from the ion source to a mass analyser. A first set of mass analysis scans are performed. Each of the first set of mass analysis scans comprises: accumulating a portion of sample ions at a point along the ion path, wherein the portion of sample ions are accumulated for a duration not exceeding the maximum accumulation duration, and mass analysing the portion of sample ions using the mass analyser. The mass analyser is a Fourier Transform mass analyser or a Time of Flight mass analyser.
