1of over tightening the nut using finger force. Usea rule to mark the column insertion distance,then cut the column. The distances for column
insertion into Shimadzu instruments are in table 1
and are calculated from the back of the ferrule.

1.	Slide the nut onto the column first, followed by
the ferrule. The flat based of the ferrule aligns
with the nut and the cone points to the detectoror injector.
2.	Using the SilTite FingerTite Install tool displayedin Figure 5, push approximately 20 mm moretubing than required through the tool. Tighten thenut, using your fingers, to seat the ferrule onto
the column, there is no need to use excessive
force, once the seal is made the column will beheld firm and will not move. There is no danger

3.	Insert the pre-assembled nut and ferrule into
the injector/detector port and screw in the nut
using finger force only - again, there is no need
to use excessive force to make a seal. You
cannot break the capillary column if you overtighten the ferrule although an over tightened
ferrule may stick to the cone of the adapter.
Remember that the ferrule will be thetemperature of the injector or FID andmay be hot. To remove an over tightened ferrule
Trajan Scientific and Medical recommends gently
levering between the shoulder of the ferruleand the relevant adapter. Under nocircumstances are wrenches or pliers
to be used on these fittings. The ferrules willseal for multiple uses as long as the length of thecolumn into the injector or FID is not changed.
