GC Injection Port Maintenance . 259
Injection Liner and Seal Cleaning or Replacement
The injection port must be warm to replace the Injection Liner and/or Seal.
1. Before heating the injection port remove the Septum Nut.
2. It is preferable to load a custom method that heats only the Injection Port. The method
should have all of the other temperatures set to off and the Injection Port set to 50°C. Allow
the temperature to reach 50°C.
3. After the Injection Port has reached 50°C grasp the Injection Liner and pull it out of the
Injection Port.
4. Remove the Liner Seal from the bottom of the Liner.
5. Replace the Liner and Seal with the new Liner and/or Seal.
6. Remove the Septum from the old Liner and insert it into the new Liner.
There are two separate Liners that can be used in the Torion T-9. There is a liner for SPME
type injections and a larger volume liner for small liquid injections.
7. Reinstall the Septum Nut. Make sure the Septum Nut is tight.
NOTE: The Liner has a deactivated surface. It can be cleaned with normal solvents like methanol or
hexane. Use of aggressive acid or base will damage the liner coating and result in poor performance
for active chemical compounds. If the Liner appears to be scratched or damaged in any way it is
recommended that the Liner be replaced.
8. Re-install the Universal Interface by positioning it with the flat side of the port lining up with
the flat side of the opening. Make sure the assembly is plugged into the board. Reinstall the
stainless steel Interface Mounting Ring Nut and the protective cover.
