b. Turn the I/R tool handle to the unlock position
to release the ion
volume from the I/R tool.

11. Verify that the ion volume is fully seated in the ion source block:
• Withdraw the I/R tool away from the ion volume about 2.5 cm (1 in.), and turn the
I/R tool handle to the lock position.
• Slide the I/R tool back into the vacuum manifold until the end of the I/R tool just
touches the ion volume.
• Test that the I/R tool does not go into the inlet valve completely, which indicates that
the ion volume is seated properly.
12. Remove the I/R tool.
a. Withdraw the I/R tool until the guide ball reaches the first stop (see
).
b. Close the inlet valve by pulling the inlet valve lever down (see
c. Loosen the inlet valve knob by turning it counter-clockwise.
d. Continue withdrawing the I/R tool completely from the inlet valve by sliding the I/R
tool through the guide ball track in the guide bar.
