5.3.1 Overview of Manual Calibration

Overview During manual calibration:

You specify a calibration reference file (.REF) that contains reference masses.

The software matches peaks by comparing observed masses in the spectrum to reference masses.

The software lists masses that match within the specified peak matching criteria, and calculates calibration constants.

You can apply the calibration constants to all spectra in a Mariner or Voyager data file.

You can apply individual calibration constants to each spectrum in a Voyager data file.
