If the correct peaks have been matched then the calibration report can be printed out:
Select Print , Print from the report display.
If insufficient peaks have been matched or the wrong peaks have been matched see
Calibration Failure later in this chapter. To accept the calibration:
Select OK from the calibration report.
The same procedure is used for the scan speed compensation except that
Scan Speed Compensation is selected in the dialog box, and the fast scanning file
is used. Note that for the scan speed compensation the default file is FASTMS1 . If an
alternative filename has been used then this must be selected using the data browser.
Once all three calibrations (static, scanning and scan speed compensation) have been
completed then the instrument can be used for any mass range within the limits of the
scanning calibrations and at any scan speed from 100 to 1000 amu/sec.
Calibrating MS2
The calibration of MS2 is carried out in exactly the same manner as above, except that
data is acquired in MS2 mode instead of MS1.
Using the Instrument
Once all six calibrations (static, scanning and scan speed compensation, each for both
MS1 and MS2) have been completed then the instrument can be used for any mass
range within the limits of the scanning calibrations and at any scan speed from 100 to
1000 amu/sec.
