About the ChemStation Software
The ChemStation may be configured for restricted access for two user access
levels, an operator and manager level. The manager level may be password
protected and allows access to the complete ChemStation functionality. The
operator level restricts the user to key functionality and executing defined
analytical methods. The operator level is intended for use in routine
laboratories and specifically prevents users from modifying and creating new
methods.
Method Robustness
Sequence summary reports (see “Sequence Summary Reporting” on page 226)
provide a means to test methods for robustness. The extended format reports
for user selected criteria, are reported as trend charts and may be used to
determine the realistic operation limits. These limits can then be incorporated
in the method to ensure, through the analysis of control samples, that the
method is operating within specifications.
System Operation
The ChemStation verification kit, which is part of the standard software,
automatically checks for the correct installation and operation of the data
evaluation parts of the software by comparing results generated when the test
is executed against prerecorded known values. The verification kit allows
users to define their own data files and methods to be the basis of the test.
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.
