20 Understanding Your Agilent ChemStation
1 Agilent ChemStation Features
About the ChemStation Software
During an analysis, the complete functionality of the ChemStation can be used
through the offline copy. While acquisition is running, the Data Analysis part
of the online session of an instrument is not accessible, and data review has to
be performed in the offline copy.
A snapshot function is available for users who wish to start processing data
before the analysis is completed. The snapshot has to be taken in the offline
copy of the instrument sessions and is immediately present for review.
The layout of the signal and status information windows, including the
components of the schematic instrument interface diagram is saved
automatically.
For further information on Data Acquisition, see “Data Acquisition” on
page 59 and the online help system.
Data Analysis — Display
The Data Analysis view extends the standard tool bar with task-grouped data
analysis functions including integration, calibration, reporting, annotation,
and signal comparison toolsets. The following key graphical operations are
possible:
• single or multisignal displays selectable when loading the
chromatogram/electropherogram,
• overlays of chromatogram/electropherogram from different samples,
• subtraction of one chromatogram/electropherogram from another,
• graphical vertical and horizontal alignment of signals to help visual
comparison,
• signal inversion or mirroring to help visual comparison,
• graphical zoom and scrolling functions,
• adjustment of display attributes including selection of tick marks,
baselines, axes, retention/migration times and compound names (the user
can also select the font for the RT and compound labels, adjust the size and
orientation of the display, select the display as overlaid or separated and
select scaling factors),
• the chromatogram/electropherogram display may include graphical
overlays of instrument parameters depending on the capability of the
configured instrument,
