Audit Trail

Audit Trail window is used for logging of individual operations of the station. By allowing backward control of all performed operations, including information about who and when it was performed, the logging of operations supports higher reliability and repeatability of results in the means of Good Laboratory Practice (GLP) rules.

Audit Trail - Session

Audit Trail window is accessible from the main Clarity window via System - Audit Trail command or from all other station windows using Window - Station Audit Trail command. Other windows, such as Calibration or Chromatogram, have their own Local Audit Trails.

Clarity station keeps three tables with logs of operations. Each of them corresponds to one tab in Audit Trail window - these are Session audit trail, Daily Audit Trail and Global.

Session Audit Trail

The audit trail logs changes from the time the station was started until the station is turned off.

Daily Audit Trail

The audit trail logs changes for each day the station was turned on.

Global Audit Trail

This audit trail is mainly for regulated environment as it keeps track about each station start, users logging to instruments, creating of daily audit trails and other important settings and file changes. Logging to this audit trail can't be turned off.
