Operation Manual 33
To Condition a Capillary Column
Materials needed
• Carrier gas, (99.9995% pure or better)
• Wrench, open-end, 1/4-inch and 5/16-inch (8710-0510)
Procedure
1 Install the column in the GC inlet. (See “To Install a Capillary
Column in a Split/Splitless Inlet” on page 31.)
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 Program the oven from room temperature to the maximum
temperature limit for the column.
4 Increase the temperature at a rate of 10 to 15 °C/min.
5 Hold at the maximum temperature for 30 minutes.
6 Set the GC oven temperature to 30 °C and wait for the GC to
become ready.
7 Attach the column to the GC interface. (See “To Install a
Capillary Column in the GC/MS Interface” on page 35.)
WARNING
The use of hydrogen gas is specifically prohibited with this product.
WARNING
The GC operates under high temperatures. To avoid burns, do not
touch any GC parts unless you are certain they are cool.
CAUTION
Never exceed the maximum column temperature, either in the GC/MS
interface, the GC oven, or the inlet.
