To reconnect the MSD to the GC

To reconnect the MSD to the GC
Wrench, open-end, 1/4-inch × 5/16-inch (8710-0510)
Materials needed:
1 Position the MSD so the end of the GC/MSD interface is a few inches from
the GC.
2 Reconnect the GC/MSD interface cable.
3 Slide the MSD to its regular position next to the GC.
Be careful not to damage the GC/MSD interface as it passes into the GC. Make
sure the end of the GC/MSD interface extends into the GC oven.
4 If necessary, slide the foreline pump back under the vacuum manifold.
The foreline pump may be located on the floor, on the lab bench next to or behind
the MSD, or under the vacuum manifold at the back of the MSD.
5 Reinstall the capillary column (page 28).
6 Pump down the MSD (page 58).
7 Turn on the GC.
Re-establish appropriate temperature setpoints for the GC/MSD interface and GC
oven.
