Restarting the System

Thermo Scientific
Note For proper alignment and sensitivity, the front manifold door should be screwed
down fully to keep the magnet alignment with the ion source correct.
11. Install the CI and calibration tubes if they are not already installed.
a. Use 1/16 in. graphite-Vespel ferrules and tighten 1/2 turn past the position that just
begins to hold the tubing firm. Do not reuse graphite-Vespel ferrules more than three
times as they can become too compressed to re-tighten if a leak is found at their seal.
b. Replace the right side cover.
12. Install the column or no-hole ferrule.
13. Ensure the transfer line is positioned correctly in the GC oven.
14. Use the source plug and the associated procedure found in
page 12 to make sure the column is placed at the edge of the ion source.
15. Close the manifold door and reattach the four screws. Confirm that front door screws
hold door completely to the manifold.
16. Reconnect the four wires that connect the rear 4-pin feedthrough to quadrupole 3 and
the collision cell assembly. See
17. Reconnect the four wires that connect the front 4-pin feedthrough to quadrupole 1 and
the ion guide. See Figure 92
18. Reconnect the collision gas tube. See
19. Put the glass manifold covers back into place. Be sure to blow off all dust from the covers
and o-ring first.
20. Reconnect the electrometer board cable.
21. Reattach the top cover and tighten the top cover panel screw.
 To restart your system
1. Close the front door of the instrument.
2. Twist the vent valve clockwise to close the valve. Be careful not to pinch the o-ring.
3. Reinsert the column to the proper length and tighten the transfer line nut. See
a Column" on page 12
4. If you are using hydrogen, replace the front panel screw.
5. Replace the ion source cartridge. See
through the Vacuum Interlock"
6. Replace all hydrogen safety screws if you are using hydrogen.
