How to Install Saturn
To install the Saturn GC/MS, proceed as follows:
1. Connect the GC to a helium source, and then purge the system filters, and
columns for 15 minutes.
2. Feed the capillary column and nut through the side of the GC. Connect the
column to the transfer line.
3. Slide the Saturn GC/MS toward the GC until the transfer line is protruding
into the GC oven.
4. Connect vacuum tubing from the rear of the Saturn MS to the foreline pump
with a clamping ring.
5. Connect the power cord from the foreline pump to the rear of Saturn. (J2
label pump power only)
6. Connect the GC serial cable to the COM1 port on the computer if using a
3400/3600 GC.
7. Connect the GC ethernet cable to the ethernet port on the computer if using
a 3800 GC. There should be a tee connector and a terminator at each end
of the 50-ohm coax cable.
8. Connect the IEEE cable to the Saturn GC/MS and the computer.
9. Plug in the GC, ms-spectrometer, and data-system power cords.
10. Switch on the power to the Saturn GC/MS, the GC, and the computer.
11. Bring up Saturn System Control on the computer.
12. Select Diagnostics.
13. Check the turbomolecular pump speed. The pump speed should reach the
100% value within 30 min of turning on the power to the mass spectrometer.
The diffusion pump should reach READY state in 30 min.
14. Bake-out the trap (250
°
C) and manifold (120
°
C) for at least 2 hours before
you tune it.
How to Move Saturn
To move Saturn, proceed as follows:
1. Using the shutdown procedure shut down the GC and mass spectrometer.
2. Turn off the GC and computer. Then unplug the GC, mass spectrometer,
and data system power cords.
