 Procedure
Always wear clean gloves while handling any parts that go inside the GC or the
C AU T I O N
analyzer chambers.
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.
1 Condition the column. (See
Electrostatic discharges to analyzer components are conducted to the side

board where they can damage sensitive components. Wear a grounded
antistatic wrist strap, and take other antistatic precautions before you open the
analyzer chamber.

7 Use the column cutter to score the column 2 cm from the end.
Do not break the column off inside the vacuum manifold. Pieces of column
