become ready.
Be careful! The oven, inlet, and/or detector may be hot enough to
cause burns. If the oven, inlet, or detector is hot, wear
heat-resistant gloves to protect your hands.
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
3 Assemble a brass nut and Vespel/graphite ferrule on each
end of the column.
Glass columns must be simultaneously inserted into the inlet
and detector and installed parallel to the oven door. When
conditioning the column, do not attach the column to the
detector.
4 If conditioning the column, insert the column into the packed
column inlet until it bottoms. Withdraw the column 1 to
2 mm. Finger-tighten the inlet column nut. (See
Condition a Packed Column"
Overtightening the column nut or forcing it to bottom in either the
inlet or detector may shatter the column.
