3 Intuvo 9000 GC Column Maintenance
To Install a Column Guard or Jumper Chip
The column Guard Chip and the Jumper Chip are both single-use, consumable
parts. Installation deforms part of the Chip to make a good seal, so that a
mis-installed Chip cannot be re- used. The Guard Chip cannot be cleaned or
conditioned.

Chip, and other components in the flow path heated zones to < 40 °C and
configures the GC. Follow the on-screen GC prompts.
The inlet, detector, bus components, and column can be hot enough to cause burns.
Cool heated zones to a safe handling temperature before continuing.
Always wear clean gloves while handling any parts that are in the flow path going to
the analyzer or parts that are located inside the analyzer.
