ChemStation Plus Security Pack — Audit-trails and change documentation
• all user comments during
reanalysis cycles, and
• a detailed change documenta-
tion of manual integration
events.
All reanalysis events and result
versions are documented in the
sample audit-trail. The sample
audit-trail creates for each result
change one new line in the audit-
trail table. It displays both the
interactive manual changes and
the system generated entries each
in a separate line. Examples for

The Agilent ChemStation Plus
Security Pack includes four audit-
trails:
• run logbooks,
• method revision history data,
• sample audit-trail, and
• database logbook.
Sequence and logbook
During data acquisition, all events
are documented in the sequence
and run logbook with date and
time stamp (figure 18). The
sequence and run logbook docu-
ments all data acquisition events
such as
• start and execution of methods
• the actual sequence line in the
sequence table,
• any failure during method
execution, and
• initialization of data spooling to
the ChemStore C/S database.
Method changes
The method changes are stored
with each current method version
including a mandatory user com-
ment for the change (figure 19).
The method audit-trail stores
• the time of change and the
operator who performed the
change
• the current method revision in
the database, and
• a mandatory comment of at
least five characters each time
the method was changed.
Sample audit trail
The sample related audit-trail,
shown in figure 20 documents
• all changes and modifications,
on one sample,
• all run versions,
