To Condition an Intuvo Capillary Column
Materials needed
• Carrier gas, (99.9995% pure or better)
• Gloves, clean, lint-free (Large 8650-0030) (Small 8650-0029)
• Tweezers (8710-2460)
• Intuvo torque driver (5190-9571)
• Intuvo gasket, polyimide 5/pk, for temperatures < 350 °C (5190-9072)
• Intuvo gasket, nickel 5/pk, for temperatures 350 °C to 450 °C (5190-9073)

Procedure
1 Install the column that requires conditioning. (See “To Replace an Intuvo
GC Column” on page 61.)
2 Set a minimum velocity of 30 cm/s, or as recommended by the column
manufacturer. Allow gas to flow through the column at room temperature
for 15 to 30 minutes to remove air.
3 Increase the column temperature to 120 °C.
4 Hold at the this temperature for 30 minutes.
5 Use MassHunter to run an air and water check. Proceed to the next step if
the air and water are within limits.
6 Program the column temperature to increase from 120 °C to the maximum
temperature limit for the column at a rate of 10 to 15 °C/min.
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.
