13. Slide the collision cell assembly onto the analyzer tray. Hold the collision cell and Q1 in
the tray and make sure Q1 and the collision cell are correctly positioned before tightening
the screws on the Q1 exit endcap
.
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 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.
