5 Score the column using a glass scribing tool. The score must
be square to ensure a clean break.
6 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.
7 Wipe the column walls with a tissue dampened with
isopropanol to remove fingerprints and dust.
8 Install the column.
If the column id is 200 um or more, push the column into
the adapter until it stops at the indentation. Pull it back
1 to 2 mm and tighten the column nut with one 5/16-inch
wrench on the adapter and another 1/4-inch wrench on the
column nut.
