2 Installing GC Columns
38 5977B Series MSD Operation Manual
Procedure
1 Condition the column. (See “To Condition a Capillary Column” on page 36.)
2 If you are not using Quick Swap, vent the MS. To vent the MS, see “Vent the
MSD” on page 77.
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 Use the column cutter to score the column 2 cm from its end.
5 While holding the column against the column cutter with your thumb, break
the column against the edge of the column cutter.
6 Inspect the end for jagged edges or burrs. If the break is not clean and even,
repeat steps 4 and 5.
7 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
until you are certain they are cool.
