Maintenance Overview
Your instrument needs servicing and maintenance to avoid contamination, which
prevents signal suppression, reduces background noise, minimizes adduct
formation, and enables the instrument to operate at its peak performance. To
achieve the most accurate results, routine and periodic maintenance is crucial.
The difference is that routine maintenance is done regularly to keep the
equipment in good working condition, while periodic maintenance is done at
specific intervals to prevent breakdowns or failures.
MassHunter acquisition software for LC/MS systems tracks the number of
injections and the number of days since a maintenance activity was performed
for your LC/Q-TOF instrument using the Early Maintenance Feedback (EMF)
dashboard. EMF allows you to plan for scheduled maintenance when it is
convenient and increase the instrument uptime. If a limit is exceeded for an EMF
item that is enabled, then the EMF icon changes to yellow, and the tooltip
displays the cause in the device pane. Set the limits for each EMF item in the
Maintenance dialog box following instructions detailed in online help.
This Maintenance chapter is broken down into maintenance procedures listed by
routine, then periodic maintenance tasks with their recommended schedule of
performance, with the EMF procedures cross referenced in the final section.
Consult the online help or contact your Agilent consultant for further information.
