What Happens When a Method is Run?
Peak Purity Checking (ChemStations for LC 3D, CE, CE/MS and LC/MS 
Systems Only)
For a peak with UV-Visible spectra, you can calculate a purity factor for that 
peak and store it in a register. Peak purity may be determined automatically at 
the end of each analysis as part of the method, if the Check Purity box is 
checked when specifying an automated library search or when selecting an 
appropriate report style. See Understanding Your Spectral Module for details.
Print Report 
A report is generated with identities and amounts of components detected in 
the run.
Customized Data Analysis (Run Time Checklist)
Enables you to run your own customized macros to evaluate your analytical 
data.
Save GLP Data (Run Time Checklist)
Saves the binary register GLPSave.Reg together with the data analysis method 
in the default data file subdirectory. This feature is designed to help prove the 
originality of the data and the quality of the individual analysis.
The GLPSave.Reg binary file contains the following information in a 
non-editable, checksum-protected, register file:
• key instrument set points (can be graphically reviewed),
• chromatographic or electropherographic signals,
• integration results,
• quantification results,
• data analysis method, and
• logbook.
