How do I install a GC column into the new Flip Seal adaptor nut?

31 Jul 2025

Insert the GC column through the 1/16” adaptor sealing nut and a standard 1/16” graphite or graphite-Vespel capillary ferrule. Make a clean cut across the GC column. Install the column into the adaptor 30-32 mm from the bottom of the 1/16” nut, which places the column end a few millimeters above the bottom of the inlet seal, the perfect installation distance! Don’t forget to leak check with a Restek Electronic Leak Detector (cat.# 28500) after tightening the adaptor nut to seal the GC column to the inlet and re-pressurizing the inlet.
