This Information Applies To: Agilent 6100 and 6400 Series LC/MS Systems controlled by OpenLab CDS ChemStation or MassHunter Workstation for LC/QQQ
How to safely vent and turn off your Agilent Single or Triple Quadrupole LC/MS system.
Tips: For single quadrupole LC/MS systems controlled by OpenLab CDS, se Turn off your Single Quadrupole LC/MS System Using OpenLab CDS
The LC/MS system will need to be vented and turned off when the instrument will be idle for an extended time or when you need to do maintenance.
Before you begin, check that the instrument has completed acquiring data or any tuning, and that you have saved all data as needed.
Steps to Follow
Caution: When you vent the instrument from within the Tune View, the LC/MS instrument does not turn off completely. Follow the entire shutdown procedure.
Warning: The spray shield and related spray chamber components are likely to be hot. Do not touch them until they have cooled to a safe temperature for handling. Always use powder-free nitrile gloves when handling LC/MS parts.
To vent the Instrument
To shut down the Instrument
Turn off the MS using the power switch located in the lower left front corner of the instrument. (Figure 1)
Unplug the main power cable leading to the LC/MS Instrument. Certain internal components are energized whenever the main power cable is connected even if the front power switch is turned off, so it is always safer to unplug this cable when venting.
If the LC/MS instrument includes a pump expander box (see Figure 2), then turn off the pump expander box and disconnect the cable that is plugged into the mains receptacle.
Caution: Despite being shut down some heated zones such as source components will still have residual heat, so wait for heated components to completely cool down before handling heated to avoid injury.
