36 Operation Manual
2 Installing GC Columns
To Install a Capillary Column in the GC/MS Interface
Procedure
1 Condition the column. (See “To Condition a Capillary
Column” on page 33.)
2 If you are not using Quick Swap, vent the MS. To vent the MS,
see “To Vent the MS” on page 69.
3 Slide an interface nut and conditioned ferrule onto the free
end of the GC column. The tapered end of the ferrule must
point towards the nut.
4 Insert the column into the column measuring tool and allow
the end of the column to project 10–15 mm past the end of
the tool.
5 Use the column cutter to score the column 2 cm from its end.
6 While holding the column against the column cutter with
your thumb, break the column against the edge of the column
cutter.
7 Inspect the end for jagged edges or burrs. If the break is not
clean and even, repeat steps 4 and 5.
8 Wipe the end with alcohol.
WARNING
The analyzer, GC/MS interface, and other components in the
analyzer chamber operate at very high temperatures. Do not touch
any part until you are sure it is cool.
WARNING
Dangerous voltages exist inside the analyzer chamber, which can
result in fatal injury. Do not open the analyzer chamber door for any
reason. If access is ever required, trained service personnel must
first disconnect the instrument from the building power source.
WARNING
The GC operates under high temperatures. To avoid burns, do not
touch any GC parts unless you are certain they are cool.
