Procedure
1 Install the column that requires conditioning. (See “To Replace an Intuvo GC
Column” on page 55.)
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.
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.
