Empower Audit Trail

Hello everyone ! I have this situation:

-first analyst finished the running of a sample set in XXX PROJECT and record the using of the HPLC in the logbook.

-second analyst run a single injection in YYY PROJECT and he DOESN´T record the using of the HPLC in the logbook.

-third analyst ran a sample set in ZZZ PROJECT and record the using of the HPLC in the logbook.

the question is: how can I detect that the second analyst ran a single injection with an audit trail viewer? Because I can see the audit trails availables are PROJECT AUDIT TRAIL and SYSTEM AUDIT TRAIL, but I think I need an Instrument audit trail in order to see "hidden" actions.

Thanks in advance
