Agilent 6500 Series Q-TOF LC/MS Maintenance Guide 15
Basic Operation 1
To start the system in Standby mode
To start the system in Standby mode
This procedure brings the system from the powered off state to Standby mode.
1 Check that nitrogen gas for the drying gas and for the collision cell are
turned on.
When you use an instrument with Agilent Dual Jet Stream Technology or
Agilent Jet Stream Technology, the drying gas requirements are greater
than when operating with ESI, APCI, APPI, or multimode sources. The
supply line must have two hydrocarbon traps (part number BHT-4 or
RMSN-4) plumbed in parallel to achieve these flows without triggering
errors at the instrument. Refer to the Installation Guide for more details.
2 Check that the rough pump is connected to the Q-TOF LC/MS.
• Check that the rough pump power cable is connected to the Foreline
Pump power receptacle behind the service panel of the Q-TOF LC/MS.
• For 6550: Check that the rough pump power cable is connected to the
Foreline Pump power receptacle and that the Ion Funnel pump is
connected to the Auxiliary Pump power receptacle in the pump
expander box of the Q-TOF LC/MS.
• Check that the rough pump has the correct voltage rating for your AC
power (230 V or 208 V).
• For 6520/6530/6538/6540: Check that the rough vacuum tubing is
connected to the inlet part of the rough pump.
• For 6550: Check that the rough vacuum hose for the foreline pump is
connected to the foreline vacuum port and that the ion funnel rough
vacuum hose is connected to the ion funnel rough pump inlet.
• Check that the switch on the rough pump is in the On position.
