16 Agilent 6500 Series Q-TOF LC/MS Maintenance Guide
1 Basic Operation
To start the system in Standby mode
3 Check that all pump and spray chamber exhausts are vented outside the
laboratory.
For oil-based rough pumps only: The oil mist filter must be installed on the
rough pump, and the ballast valve must be closed. Open the ballast valve
periodically (must be done on a weekly basis) to return any oil that has
condensed in the oil mist filter to the pump as needed.
For dry pumps (Agilent TS800 or Edwards XDS351i), the ballast does not
need to be emptied regularly.
4 Turn on the power for the computer and monitor.
5 Check that the instrument is plugged into a power outlet.
6 For 6550 only: Check that the power switch on the pump expander box is
connected to the wall outlet and is turned on. The switch is illuminated
green when the power is on.
7 Turn on the front switch of the Q-TOF LC/MS.
This starts the pumping system and the electronics.
8 After Windows starts, click Start > Programs > Agilent > MassHunter
Workstation > Acq Tools > Q-TOF Diagnostics to start the Q-TOF
diagnostics program.
9 From the Connection menu, select Connect and click OK.
A silicone rubber septum is placed between the spray shield and the capillary for shipment.
Make sure that this rubber septum is removed if you are starting the system for the first
time.
Do not connect the spray chamber exhaust bottle to the rough pump exhaust tubing or
the rough pump exhaust tubing to the spray chamber exhaust tubing. Doing so can
contaminate the instrument with rough pump fluid.
Vent all exhausts external to the building where they cannot be recirculated by
environmental control systems. Do not vent exhaust into your laboratory. The exhaust
fumes from the vacuum pumps and spray chamber contains trace amounts of the
chemicals you analyze. Health hazards include chemical toxicity from solvents, buffers,
samples and pump fluid vapor, as well as potentially biohazardous aerosols of
biological samples.
