Intuvo 9000 GC Column Maintenance
Handling the Intuvo 9000GC Column and Bus Components
The Agilent Intuvo 9000 Gas Chromatograph (Intuvo 9000 GC) does not use
traditional ferrules and nuts for most column and flow path seals. In a
traditional gas chromatography connection, the seal is made by deforming a
soft ferrule around the periphery of a column or tube, with a second seal made
between the ferrule and the fitting. Instead, the Intuvo 9000 GC click and run
connections use a sealing system based on contact between flat surfaces.
Compared to traditional ferrule seals, these connections are leak-free and easy
to make.
When making these seals, follow a few simple guidelines:
• Do not touch the click and run sealing surfaces with bare skin or dirty
• Use only the provided Intuvo 9000 GC torque driver to tighten Intuvo
• Avoid scratching or deforming click and run sealing surfaces.
• If you need to clean a sealing surface, use clean, compressed air.
• Use a new gasket each time you install a column or Intuvo chip.
