To Cut a Loop from a Column
1 Gather the following:
• New ferrule(s) for the column inlet connection
• Column cutter
2 Place GC in maintenance mode: Maintenance > Instrument > Perform Maintenance >

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 safety glasses to protect your eyes from flying particles while handling, cutting, or
installing glass or fused silica capillary columns. Use care in handling these columns to
prevent puncture wounds.
3 Loosen the inlet column nut and remove the column from the inlet.
4 Uncoil one loop of column from the column hanger.
5 Cut the unwanted loop from the column.
6 Install the column into the inlet using the new ferrules.
Perform the installation procedure manually. Do not use the automated column installation
wizard.
