Abstract

A calibration function for time-of-flight mass spectrometers that converts ion times of flight into mass to charge ratios, takes into account not only the time of flight of a specific ionic species, but also the ion signal intensity of that ionic species. Use of the conversion function reduces nonsystematic deviations of the calculated mass values from the true mass values previously experienced in time of flight mass spectrometers.
