24. Close the front door of the GC.
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 ISQ Spare Parts Guide for information about ordering these
ferrules.
25. Condition the graphite Vespel ferrule:
a. Raise the oven temperature to the maximum temperature you will operate the GC
column.
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.
d. Retighten the transfer line nut.
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. Twist the vent valve clockwise to close the valve. Be sure not to pin. the O-ring.
d. If you are using hydrogen as a carrier gas, replace the front panel screw.
e. Replace all remaining hydrogen safety screws if you are using hydrogen.
27. Power on the mass spectrometer.
WARNING - FIRE HAZARD: If you are using hydrogen, do NOT reach over the top of the
instrument to power it on. Instead, reach around the side or go to the back of the
instrument and flip up the power switch.
28. Once the instrument is pumped down and able to scan, click Air & Water / Tune on the
Dashboard 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.
You can attach now attach all the capillaries to the microfluidics splitter.
