Data Traceability, Originality and Quality
Run-time logbook provides a transaction log of the complete system. It also
records any unusual events (such as errors or parameter changes made during
a run) as well as the instrument conditions before and after each analysis. A
copy of the relevant logbook extract is saved with each data file.
The actual instrument conditions, such as pressure, flow, and temperature,
that occurred during each analysis are also recorded if the configured
instrument supports this capability. This data can be subsequently displayed
graphically with the chromatogram/electropherogram to show the actual
instrument conditions during that particular analysis, as well as being
included on the report.
Methods saved with the data file record the actual method at the time of the
analysis and allows the complete reconstruction of the reported data at a later
date. The method is saved at the completion of all the analytical steps.
All reports have time stamps and traceable page numbering (page x of y
pagination style). The user may select the level of detail in each report ranging
from simple summary reports to complete system details (see the Reporting
section above).
GLP Save register files, specified as part of the method configuration, save all
the original data, including sample information, data analysis method,
chromatographic/electropherographic signals, instrument conditions,
integration and quantification results, report data and the run logbook in one
checksum protected binary file. This is an uneditable binary format that
ensures the originality of the results.The file includes a revisioning scheme
that indicates if data has been reprocessed.
Control sample types may be defined in the sequence table and used to
automatically check the instrument performance against quality control
sample results when the instrument is running unattended. Results that are
outside the user-specified acceptable range will stop the automatic execution
of the instrument.
