b. On the TSQ 9610 Dashboard set the MS transfer line temp to 40 °C and the ion
source temp to 175 °C (to avoid excessive oxidation of source parts or contamination
from the V-lock source plug).
2. Using the source removal tool and vacuum interlock, remove the ion source cartridge. See
the TSQ 9610 Hardware Manual for instructions to remove the ion source cartridge.
3. Place the ion source cartridge on the source holder and set aside.
4. Place the V-lock source plug in the source plug holder.
5. Attach the source exchange tool to the V-lock source plug in the source plug holder.
6. Twist the plug until it aligns securely in the grooves in the source exchange tool and
remove the plug from the holder. The V-lock source plug is securely attached to the
source exchange tool when the alignment grooves on each piece match up.
Figure 22. Attaching the V-lock Source Plug to the Source Exchange Tool
Note Use compressed air to blow all the dust off the V-lock source plug before inserting it
into the mass spectrometer.
7. Once the ion source temperature has dropped below 200 °C, insert the barrel end of the
source exchange tool into the vacuum interlock and twist it clockwise to lock the source
exchange tool into position. Be sure the black handle remains fully extended and locked.
Note If the ion source temperature is above 200 °C, parts of the ion source or the V-lock
source plug could oxide and be damaged, causing leaks in the MS system.
8. Evacuate the VPI.
a. Confirm that the source removal tool is properly engaged in the VPI.
b. Press the blue Evacuate button on the front of the instrument.
c. The Evacuate light will begin to flash green, and should continue to flash green for
approximately 20 seconds.
9. If the pressure has returned to an acceptable value after the 20-30 second wait, the
evacuate light will turn off and the Ready to Open light will be solid green. At that point,
