To Correct Leaks in the Packed Column Inlet
If the inlet fails a pressure decay test, check the following:
• Check the caps/plugs used in the test—make sure each is
correctly installed and tight.
• If you performed the leak test after performing maintenance,
check for proper installation of the part(s) handled during
the maintenance.
• Check the tightness of the septum nut. See To change the
septum on the purged packed inlet. See To change the
septum on the purged packed inlet.
• Check the septum. Replace if old or damaged.
• Check that the top insert weldment is installed tightly.
• Replace the O-ring. See To change the O-ring on the purged
packed inlet. Also check the glass insert. See To change the
glass insert on a PP inlet.
• Replace the ferrule seal on the adapter.
• Make sure the inlet temperature remained constant during
the test.
If these items do not resolve the problem, contact Agilent for
