Separating The Transfer Line From The Source Heater Block; Removing The Transfer Line - Thermo Scientific TSQ 9000 Hardware Manual

20. Once the transfer line is separated from the source heater block, pull the transfer line back
so that it slides to the end of the standoffs. The tip of the transfer line should be far from
the analyzer tray. The calibration gas tubing may need to be bent slightly for the transfer
line to be pulled all the way back (this is easier to do if no calibration gas tubing is
attached). If the tubing is being replaced, the graphite/Vespel ferrule will also need to be
replaced.
Figure 100. Removing the Transfer Line
21. Proceed with removing the collision gas tube, disconnecting all electrical connections,
and removing the analyzer tray. Be very careful to not scratch the end surface of the
transfer line, as this can ruin the sealing surface and cause the source plug to not seal
properly to the transfer line surface. This will cause leaks and can render the source plug
useless.
22. Remove the heat shield and wedge it between the source interface board and the wall of
the manifold to disconnect the board from the 20-pin feedthrough.
23. Remove the bottom right screw holding the tray to the manifold.
