5975 Series MSD Troubleshooting and Maintenance Manual 103
To Separate the MSD from the GC
Materials needed
•
Wrench, open-end, 1/4-inch × 5/16-inch (8710-0510)
Procedure
1 Vent the MSD.
2 Turn off the GC.
3
Remove the capillary column from the GC/MSD interface.
4
The foreline pump may be located on the floor, on the lab bench next to or
behind the MSD, or under the analyzer chamber at the back of the MSD.
Move it as needed to provide slack in the tubing and cables.
5
Move the MSD away from the GC until you have access to the GC/MSD
interface cable (
Figure 9 ).
6
Place a column nut with a blank ferrule on the end of the interface. This
will help keep contamination out of the MSD.
7
Disconnect the GC/MSD interface cable. Disconnecting the cable with the
GC on can cause a fault condition.
8
Continue to move the MSD until you have access to the part requiring
maintenance.
WA R N I N G
Make sure the GC/MSD interface and GC oven have cooled before you remove the
column.
