6 Score the column using a glass scribing tool. The score must be square to ensure a clean
break.
7 Break off the column end by supporting it against the column cutter opposite the scribe.
Inspect the end with a magnifying loupe to make certain there are no burrs or jagged
edges.
8 Wipe the column walls with a tissue dampened with isopropanol to remove fingerprints
and dust.
9 Position the column so it extends 1 to 2 mm above the end of the ferrule. Slide the septum
up the column to hold the column nut at this fixed position.
