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/MSD interface, and other components in the analyzer
WAR N IN G
chamber operate at very high temperatures. Do not touch any part until you
are sure it is cool.
1 Condition the column.
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
required, trained service personnel must first disconnect the instrument from
the building power source.
2 Vent the MSD and open the analyzer chamber. (See
