Correcting time-of-flight drifts in time-of-flight mass spectrometers

摘要

A method of correcting time-of-flight drift in a mass spectrometer by identifying mass spectral peaks of ions in spectra, detecting ions having substantially the same mass across spectra, determining a time-of-flight drift of the detected ions, and correcting the time-of-flight drift of the detected ions by applying a correction factor to each respective time-of-flight.
