Treatment of manual integration events
Manual integration events, e.g. a manually drawn baseline, are even more
data file specific than timed integration events. In case of complicated
chromatograms, it is highly desirable to be able to use these events for
reprocessing.
Therefore, in ChemStation B.04.01 and higher, manual integration events
can be stored directly in the data file instead of the method. At any time
the data file is reviewed or reprocessed, the manual events in the data file
are automatically applied. A run containing manual integration events is
marked in the navigation table in the corresponding column.
In addition to the tools for drawing a baseline and deleting a peak
manually, three additional tools are available in the user interface to
• Save manual events of the currently shown chromatograms into the
• Remove all events from the currently shown chromatograms,
• Undo the last manual integration events (available until the event is
When continuing to the next data file during review in the Navigation
Table, ChemStation will check for unsaved manual integration events and
ask the user whether he wants to save the events.
Manual events stored in the data file during review in the navigation table
do not interfere with manual integration events stored during review in
the Batch mode. These two ways of review are completely separated with
regard to the manual events of a data file.
In ChemStation revisions prior to B.04.01, manual integration events could
only be stored in the method. In B.04.01, this workflow can still be used.
The Integration menu in Data Analysis view provides the following items in
order to handle manual integration events with the method:
Update Manual Events of Method: Save newly drawn manual events to the
method.
Apply Manual Events from Method: Apply the manual events currently saved in
the method to the currently loaded data file.
Remove Manual Events from Method: Delete the manual events from the
method.
