Abstract
A method of determining the mass-to-charge ratios of ions in a sample is disclosed. The method includes determining a data acquisition time, where the data acquisition time is a predetermined fraction of the greatest time of flight. The method also includes providing ions from a continuous beam of a sample to a time-of-flight mass analyzer at pulse intervals having a duration equal to the predetermined fraction of the greatest flight time. The method also includes measuring a peak width and a flight time value for each of the ion species in the sample after summing the data acquired during several pulse intervals and correcting the measured flight time values according to a correlation of measured peak width values with calibration data of peak width versus flight time.
