Method Three
If you do not have an inlet valve, follow these steps:
1. Remove the DSQ II front and top covers to get a better view of the column.
2. Remove the vacuum manifold cover, as described in “Removing the Vacuum Manifold
Cover” on page 32 .
3. Remove the ion source, as described in “Cleaning the Ion Source Components” on
page 38 .
4. Adjust the column so that it extends 1–2 mm past the end of the transfer line.
5. Tighten the transfer line nut and transfer line union.
6. Replace the ion source, as described in “Cleaning the Ion Source Components” on
page 38 .
7. Replace the vacuum manifold cover.
8. Reattach the DSQ II front and top covers.
9. Condition the transfer line ferrule. Graphite/vespel ferrules like the transfer line ferrule
require conditioning to ensure a leak-tight seal.
a. Raise the oven temperature to the maximum temperature you will operate the
column (normally 300 °C).
b. Wait 10 minutes.
c. Lower the oven temperature to 30 °C and allow it to cool before continuing.
d. Re-tighten the transfer line nut and the transfer line union.
10. Set up the TRACE GC Ultra.
a. Make sure the column does not have any sharp bends and that it does not touch any
metal objects or walls inside the oven.
b. Raise the oven temperature to the initial temperature you will use (normally 40 °C).
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.
Note Turn on vacuum compensation (under the Right or Left Carrier menu).
