4.4Proper Placement of graphite Ferrules
4.4.1 Placing graphite ferrules on the column
Graphite ferrules are required for proper sealing. Follow these procedures to place one fer-
rule at each end of the capillary column.
The graphite adjuster marked with an “S” or “F” to indicate whether it is for the injection port
or detector side.
S: For Split/spiltless injection port
F: For FID (detector)
(1) Remove the wire from a new graphite ferrule. Slide the graphite ferrule on the capillary
column.
(2) Pull the capillary column through the column insertion jig so that 10 mm of column
protrudes. Tighten the column nut to fasten the ferrule to the column at that position
(tighten the column nut by hand, then 3/4 turn further with two wrenches in opposition).

(3) Because graphite may be present on the column end, the column must be clipped as
shown below.
(a) Clip the column so it is flush with the and of the jig.

(b) The edge of the cut must be completely straight.

WARNING
Wear safety glasses when handling the capillary column, to prevent
eye injuries
