Note If you are using a SilTite ferrule, follow the instructions that come with SilTite
ferrules. If you are using a graphite Vespel ferrule, they require conditioning to ensure
a leak-tight seal. See the spare parts guide for information about ordering these
ferrules.
24. Condition the graphite Vespel ferrule:
a. Raise the oven temperature to the maximum temperature you will operate the GC.
b. Wait 10 minutes.
c. Lower the oven temperature to 40 °C (104 °F) and allow it to cool before continuing.
WARNING BURN HAZARD: The oven may be hot. Allow it to cool to room temperature
before opening it. The injector will still be hot, so do not touch it.
ATTENTION RISQUE DE BRÛLURE : le four peut être chaud. Laissez-le refroidir à la
température ambiante avant de l'ouvrir. L'injecteur sera toujours chaud, donc ne le touchez
pas.
d. Retighten the transfer line nut.
25. Close the front door of the GC.
26. Restore working conditions.
a. Raise the oven temperature to the initial temperature that you will use.
b. Turn on vacuum compensation on the GC.
c. Power on the TSQ 9000 instrument.
Once the TSQ 9000 instrument is pumped own and able to scan, view air water spectra and
look for evidence of leaks with a large m/z 28 signal. If you observe a leak, stop scanning and
gently tighten the nut in small increments until no leaks appear when scanning.
If your TSQ 9000 system has a VPI and has an ExtractaBrite ion source installed, follow the
instructions below to change the column.
 To replace the column on a TSQ 9000 system with a VPI and an ExtractaBrite ion
source installed
1. Cool the oven, transfer line and ion source:
a. On the GC, set the Oven to Off.
