DAD data.
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.
