Installing the Ion Volume
Install an ion volume after cleaning or when you change ionization modes.
Y To install the ion volume
1. Place the clean ion volume on the I/R tool with the arrows aligned. See Figure 48.
2. Turn the I/R tool handle to the lock position, .
3. Install the guide bar:
a. With the guide ball track facing left, insert the guide bar into the entry housing (see
Figure 41 on page 74).
b. Push the guide bar in as far as it will go, and then rotate it 90° clockwise to lock the
guide bar into the entry housing.
4. Prepare the inlet valve for insertion:
a. Make sure the inlet valve is closed. Figure 42 shows the inlet valve lever, closed in the
down position.
b. Loosen the inlet valve knob counterclockwise and remove the inlet valve plug. The
inlet valve plug prevents air from entering the vacuum manifold in case the inlet valve
is inadvertently opened.
5. Choose Start > Programs > Thermo Instruments > TSQ > TSQ Tune to open the EZ
Tune window.
6. Click the Probe button, , in the EZ Tune toolbar. The Insert Probe message
appears. See Figure 43.
7. Inset the I/R tool into the inlet valve:
a. Insert the guide ball into the guide ball hole.
b. Slide the I/R tool forward into the inlet valve until the guide ball is at the guide bar’s
first stop. See Figure 44 on page 76.
c. Tighten the inlet valve knob clockwise to ensure a leak-tight seal.
8. Click OK. The forepump evacuates the inlet valve. Wait until you can safely insert the
probe (Figure 45 on page 76); then click OK.
9. Once evacuation is complete, pull the inlet valve lever up to open the inlet valve.
Note Wear clean, lint- and powder- free gloves when you handle a clean ion volume.
CAUTION To avoid damage to the ion source, make sure to align the arrows on the
I/R tool and ion volume.
