3 Installing Intuvo 9000 GC Column
To Replace the 9000 GC/MS Tail
7000/7010 Series TQ GC/MS Operating Manual 63
5 Unscrew the knurled tip seal retainer from the tip seal holder and remove the
tip seal, spring, and knurled tip seal retainer from the GC/MS interface. (See
“GC/MS interface tip seal” on page 69.)
6 Ensure the MS is properly aligned with the GC. If the GC/MS is not properly
aligned, the transfer line clamp screw will be difficult to tighten.
7 Open the GC front door.
8 Open the bus door and remove it by lifting the door vertically off its hinge
pins.
9 Using the Intuvo torque driver, remove the compression bolt that secures the
9000 GC/MS Tail click and run bus connection. Also remove the bolt from the
empty bus connection. (See Figure 13.)
10 Open the MS tail heater assembly by loosening the thumb screw at the top of
the clamp and rotating the clamp down.
11 Push the MS tail heater assembly back a few millimeters. A magnet will hold
the heater assembly away from the 9000 GC/MS Tail.
12 Remove the 9000 GC/MS Tail from the transfer line and bus. (See Figure 14
on page 64 and Figure 15 on page 64.) If the ferrule becomes stuck, press a
pointed object, like a paper clip, into the ferrule release hole at the end of the
transfer line.
