System Operation - Waters Xevo G2 QTof Operator's, Overview And Maintenance Manual

The IntelliStart Fluidics system consists of these components:
• A sample delivery system, with a pump, sample selector valve, and
diverter valve used for LC and probe connections.
• A lock-spray system, with a pump capable of ultra-low flow rates, a
lock-spray selector valve, flow sensor, and grounded union. The
grounded union protects the flow sensor from probe voltages. The flow
sensor regulates flow down to the very low volumes required by the
NanoLockSpray source.
• Three, shared, 30-mL sample reservoir bottles: A, B, and C.
• Plumbing for shared wash and waste bottles.
The sample reservoirs are mounted on the instrument's front panel. When you
select a solvent from the Instrument Console, a light-emitting diode (LED)
illuminates the appropriate reservoir. You can simultaneously illuminate all
three reservoirs or extinguish the LEDs for light-sensitive samples.
Recommendation:
lock-spray solution, and reservoir C for the calibrant solution.
The wash reservoir and (optionally) the reservoirs containing the lock-mass
reference solutions are external to the instrument; typically they are bottles
on the LC system. The waste reservoir is normally a bottle stored under the
instrument bench.
During normal operation the instrument access doors should be kept closed.

System operation

You configure the IntelliStart Fluidics system using the console software
where you can edit the parameters, frequency, and extent of the automation.
See the mass spectrometer's online Help for further details on operating the
IntelliStart Fluidics system.
During auto-calibration, the software automatically controls lock mass and
sample delivery.
Use reservoir A for the sample solution, reservoir B for the
IntelliStart Fluidics system 1-13
