' flag.The external calibration is used to convert flight times into m/z- values with the help of external calibrant spectra containing e.g. a polymer like polylysine. For the calibrant spectra, the calibration constants the machine uses need to be known as well as the expected masses. Then a quadratic function is fitted to convert the flight times into m/z-values.
The internal calibration uses reference masses in the spectra to correct the m/z-values using a linear function.
