Place a septum, capillary column nut, and ferrule on the
column.
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 10 to 12 mm above the
end of the ferrule. Slide the septum up the column to
hold the column nut at this position.
