Install the column that requires conditioning. (See
GC Column" on page 61.)
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.
Increase the column temperature to 120 °C.
Hold at the this temperature for 30 minutes.
Use MassHunter to run an air and water check. Proceed to the next step if
the air and water are within limits.
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.
