Chapter 5 Examining Spectrum Data

The calculated calibration constants can be exported to a
.CAL file for use with other data files. You have two options for exporting:
•Export the current calibration— Click Export in the Manual Mass Calibration dialog box to calculate and export the current calibration constants from the masses displayed in the Peaks Matched list in the Manual Mass Calibration dialog box.
NOTE: The calibration constants saved in the .CAL file are not calculated from the active trace on the screen or taken from the calibration in the data file. They are calculated from the listed masses.
•Export a calibration from a previously calibrated data file— Open an existing data file, then export the calibration constants in a .CAL file. See “Exporting .BIC,
.MSM, and .CAL files” on page
You can apply calibration constants from a .CAL file to any data file. To apply the new constants from a mass calibration file to a different file:
1.Display the spectrum to calibrate.
2.From the Process menu, select Mass Calibration.
3.Select Import Calibration.
NOTE: If you are importing a calibration into a Voyager data file, see “Importing a calibration” on page
4.Select the .CAL file to use, then click Open.
The software displays the calibrated spectrum with an MC trace label.
