Agilent ChemStation Features

About the ChemStation Software
• user-defined annotations may be interactively added to the display, with
the selection of font, size, text rotation and color (once defined, the
annotations may be graphically moved, edited or deleted),
• copy the display to the Windows clipboard in both metafile and bitmap
format,
• a pick mode function to display the values of individual data points in
detector units, and
• export of time/intensity digitized points to the Microsoft Windows
clipboard.
Data Analysis — Integration
The ChemStation integrator algorithm is the second revision of a new
generation aimed at improved ruggedness, reliability and ease-of-use.
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.
