29. Once the instrument is pumped down 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.
 To connect the column using the regular transfer line nut
Note For best results, we recommend you use the spring loaded transfer line nut. See

1. Lower the oven temperature and allow it to cool.
2. If the TSQ 9610 system is running, shut down and vent it. See the instrument's hardware
manual for instructions.
CAUTION BURN HAZARD: The injector, detectors, oven, and transfer line may be hot.
Allow them to cool before touching them.
AVERTISSEMENT RISQUE DE BRÛLURE : l'injecteur, le four et la ligne de transfert
peuvent être chauds. Laissez-les refroidir à la température ambiante avant de les toucher.
3. Unwind about one turn of the column from the column outlet end.
Note Wear clean, lint- and powder-free gloves when you handle the column and
transfer line ferrule.
4. Wipe approximately 300 mm (12 in.) of the column with a tissue soaked in methanol.
5. Choose an appropriate ferrule for the outer diameter of your column.
Note If the maximum oven temperature in your method is ≥ 290 °C (554 °F),
Thermo Fisher Scientific recommends using a spring loaded transfer line nut with a
graphic Vespel ferrule or a SilTite™ nut and ferrule. By cycling the oven at and above
this temperature, expansion and contraction of the graphite Vespel material can cause
leaks in the transfer line.
6. Insert the column through the transfer line nut and ferrule, entering through the tapered
end of the ferrule. Wipe the column again with a tissue soaked in methanol.
