5 Unscrew the tip seal from the tip seal holder and remove the tip seal and
spring from the GC/MS interface. (See “Interface tip seal” on page 70.)
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.
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.
