To Change the Ion Source on the RIS Probe Extraction Tool

This procedure is part of an automated series of steps
controlled by MassHunter. Do not attempt this procedure unless
prompted by MassHunter. The RIS Status area on the GC/Q-TOF
Tune tab must show the Gate Valve is Open and the RIS vacuum as
0.000 Torr.
If not done correctly, source maintenance can introduce contaminants
into the MS. Always wear clean rubber gloves when handling the
source.

1
Undo the latch on the right edge of the RIS cooling chamber.
2 Swing open the RIS cooling chamber until the RIS handle is
parallel with the front of the instrument.
3 Lock the RIS cooling chamber in the open position by
opening it enough to engage the locking pin on the hinge.
The 7200 Q-TOF GC/MS operates at high temperatures. Make sure
the source is cooled to a safe temperature before attempting to
remove it from the RIS cooling chamber.
4 Grasp the RIS handle with one hand, and the ion source body
with the other hand.
5 While holding the ion source steady, turn the RIS handle
counter clockwise so that the alignment guide is in the two
o'clock position. This guides the pin on the RIS bayonet out
of the track on the ion source body.
6 Gently pull the ion source free from the RIS bayonet and set
aside.
7 Remove the new ion source from its storage container. The
ion source remains connected to the lid. Twist the lid
clockwise to separate the ion source from the lid.
8 Turn the RIS handle so that the alignment guide is in the two
o'clock position.
