CAUTION - INSTRUMENT DAMAGE Do not overtighten the endcap screws. If torque
exceeds 1.5 N•m, thread damage will occur.
IMPORTANT For optimal performance, the quadrupole ceramics must fit straight and
securely in the endcap and be aligned so that the collision cell is level with the tray.
Slightly tighten each screw several times going from one to another until all are securely
tightened.

another while tightening the screws.
18. Reattach the Q3 exit lens assembly and Q3 to the analyzer tray. Ensure that quadrupole 3
and the collision cell assembly are correctly positioned before tightening screws.
19. Reattach the two screws on each side of the quadrupole rod endcaps.
Tip The endcaps have cutouts that you should use to check to be sure the ceramics are
aligned properly before attaching the two screws.
