the Purged Packed Inlet” on page 68.)
• Replacement glass liner
• Replacement septum
• Solvent that will clean the type of deposits in your
inlet
• Compressed, filtered, dry air or nitrogen
• Beaker
• Cleaning brushes—The FID cleaning kit (part number

• Lint- free gloves
2 Load the inlet maintenance method and wait for the GC
to become ready.
3 Remove the column.
4 Remove the septum nut and septum.
5 Remove the top insert weldment.
6 Remove the glass liner and O- ring.
7 If used, remove the adapter.
8 Ultrasonically clean the septum nut, top insert weldment,
and adapter (if used) in a suitable solvent.
9 Place a beaker in the oven under the inlet to catch the
solvent.
10 Soak a cleaning brush with the solvent and vigorously
scrub the interior walls of the inlet.
Be careful! The oven and/or inlet may be hot enough to cause
burns. If the inlet is hot, wear heat-resistant gloves to protect your
hands.
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
