Purge Time—When the leak test has been completed, air is
purged from the tube prior to heating it for desorption. This is
done to reduce the risk of adsorbent or analyte oxidation during
desorption. The sample tube is purged with carrier gas for the
duration of the Purge Time. The minimum purge time is 1
minute in increments of 0.1 until 999.9.
Desorb Time—During the Desorb Flow Time the tube oven is
placed around the sample tube and tube is heated with a
continuous flow of carrier gas transferring the sample from the
tube to the cold trap. The minimum desorb time is 1 minute in
increments of 0.1 until 999.9.
Trap.—Pressing the Trap button calls up a Trap Timing dialog
box Temperature showing Hold Time and Desorb Flow Time.
