Verification
Once a full instrument calibration is in place
it is not always necessary to repeat the full
calibration procedure when the instrument is
next used. Instead a calibration verification
can be performed. (There is no benefit in
verifying each calibration individually,
re-calibration is just as quick.)
If a scanning acquisition is to be made and
the calibration is to be checked:
Set up the instrument and access the
calibrate dialog box as though a full
calibration is to be carried out.
Set all peak matching parameters to the
values that were used for the calibration.
Bring up the Automatic Calibration
dialog box by selecting
Start... on the
Calibrate dialog box.
Select
Scanning Calibration
and deselect
Static Calibration and
Scan Speed Compensa
tion
.
Deselect
Acquire & Calibrate
and
select Acquire & Verify
and Print Report.
Select either
MS1
or
MS2
,
depending on the type of
acquisition to be
performed.
Select
Acquisition Parameters
to call up the Calibration
Acquisition Set-up dialog
box, as shown.
The parameters entered should be identical to the parameters originally used for
the calibration being verified.
