About the ChemStation Software
Data Analysis — Quantification
The ChemStation’s calibration mode of the data analysis view allows
simultaneous display of:
• the signal or signals being calibrated with an indication of the current
compound’s retention/migration time window,
• the calibration table whose display may be configured from a
comprehensive selection of calibration parameters, and
• the calibration curve for the compound being calibrated.
All the calibration mode windows are linked so that changes in one are
automatically reflected in all the others. This mode allows graphical selection
and modifications of the calibration data.
Quantification is based on %, Normalized %, External standard, External
standard %, Internal standard and Internal standard % calculations calculated
on either peak area or height. Calibrations may be multilevel and include
multiple internal standard definitions. Calibration histories are automatically
saved and can be used to weight the recalibration calculations.
For information on calibration and quantitation, see “Calibration” on
page 141.
Data Analysis — Data Review, Data Reprocess and Batch Review
The following two additional toolsets are available within the Data Analysis
view :
• Navigation Table
• Batch Review
The Navigation Table makes possible several key graphical operations:
• standard table configuration features, such as sorting, drag-and-drop
options, column selection, item grouping to specify a preferred navigation
table configuration
• right mouse click functions to load a signal, overlay a signal, export data,
print reports
• review signal details by expanding a line in the navigation table
