Abstract
A technique for analyzing ions by determining the time of flight of the ions in a time of flight mass spectrometer using internal calibration. In the technique, a calibration step includes the steps of launching a packet of ions from a source to a detector, detecting the time needed for the ions to arrive at the detector to obtain a time-of-flight mass spectrum, and selecting data from the mass spectrum corresponding to a plurality of ions of consecutive masses and use the selected data to determine the relationship between time of flight data and the masses of the ions of consecutive masses for calibration of the relation between times of flight and masses in the mass spectrometer.
