Recalibration
Ways to Recalibrate
Recalibration can be done in two ways using the ChemStation software. You
can recalibrate interactively or automatically during a sequence of automated
analyses. Interactive recalibration is when you directly go through the process
of recalibration using the ChemStation software after injecting one or more
calibration samples. Recalibration using a sequence is where you specify when
the recalibration occurs, but the automation software does the recalibration.
For more information refer to “Automatic Recalibration” on page 179.
For information on how to perform recalibration using the software, see the
How To part of the help system.
Recalibration of Unidentified Peaks
There are three ways to recalibrate unidentified peaks.
No Recalibration
If a peak in the calibration table cannot be identified in the integration results,
the calibration is aborted. If this occurs in a sequence, the sequence is also
aborted.
Partial Recalibration
This feature allows the recalibration of only the identified peaks. If peaks are
missing, the calibration is not aborted but the report is annotated that peaks
are missing.
Recalibration of all Retention/Migration Times
This feature allows the retention/migration time recalibration of all identified
and unidentified peaks. This is done by using the retention/migration times of
the identified peaks. There is no update of response factors for unidentified
peaks.
