Understanding Your Agilent ChemStation 211

Data Review, Reprocessing and Batch Review

Review Functions

Data files can be displayed in one of two ways:

• manually, by selecting a run to display from the table,

• automatically, with a predefined interval between each data file. During

automatic display, only those sample types displayed in the table are

displayed; the runs are displayed in the order in which they appear in the

table. The automatic review can be paused and later resumed, or stopped.

The standard functions provided by the ChemStation are available with batch

review. This includes calibration, manual manipulation of chromatograms, for

example by smoothing or manual integration. Any changes made to a data file

can be marked and saved with the batch file. Chromatograms that have been

reviewed are marked with an asterisk in the batch table. You can also discard

changes made to either the current chromatogram only, or all changes to all

chromatograms in the batch.

When a run is loaded, the selected processing options are performed; if the

run has already been processed and the changes saved, the processed run is

loaded. This is a faster process than loading the unprocessed run, because no

processing needs to be done.

Calibration in Batch Review

Calibration in batch review works independently from the recalibration

settings in the sequence table. The first step in batch calibration always

replaces both response and retention time entries in the calibration table. For

the following calibration standards, both response and retention time values

are averaged.
