26 Agilent 6500 Series Q-TOF LC/MS Maintenance Guide
1 Basic Operation
To install an electrospray source
To install an electrospray source
1 Install the ESI spray shield.
Make sure the small hole is at the top (“12 o'clock position”). If needed, use
a T10 Torx drive to loosen the two screws in the end plate, and rotate the
ESI spray shield clockwise until the hole is in the correct position. Gently
tighten the Torx screws again.
2 Install the electrospray spray chamber.
3 Close the spray chamber.
4 Connect the nebulizing gas tubing and LC tubing to the analytical nebulizer.
5 Connect the nebulizing gas tubing and LC tubing to the reference nebulizer.
6 In the left side of the Q-TOF tab, in the Method Editor window, select Dual
ESI as the Ion Source.
7 Click Apply.
The title bar of the Q-TOF instrument module in the Instrument Status
window changes from a red to a gray color.
8 Right-click the Q-TOF device pane in the Instrument Status window, then
click On to turn on the instrument.
9 While you wait for the source to reach its working temperature, continue to
create the acquisition method, or load a previously stored method.
If you load a method that was stored when using a different ion source, the
Q-TOF instrument status turns red. Repeat step 6 and step 7 to enable the
current source, and then save the method.
When the source reaches its working temperature, you can use the
instrument for analysis.
Do not touch the nebulizer tip to any surface. The needle is not protected. If you
damage the needle, you get bad system performance.
