d. Insert the precolumn in one of the two external positions of the three-way connector.
e.
Finger-tighten the precolumn retaining nut until it starts to grip the precolumn.
f.
Use the 5 mm wrench to tighten the retaining nut. Use enough pressure necessary to
obtain a good seal without overtighten.
5. Connect the precolumn to the injector base.
a.
Slide the M6 nut and the graphite ferrule onto the fused silica precolumn with the
bevelled end facing towards the injector.
b. Cut 1 cm from the precolumn.
c.
Insert the precolumn into the injector and slide the ferrule up to the injector base.
Insert the precolumn till it reaches the mechanical stop, than drawn it back of 1 mm.
d. Finger-tighten the precolumn retaining nut until it starts to grip the precolumn.
e.
Use the 1/4-in. wrench to tighten the retaining nut. Use enough pressure necessary to
obtain a good seal without overtighten.
6. Connect the capillary column to the three-way connector.
a.
Place the capillary column on the column support.
b. Slide the 1/32-in. nut and the proper Vespel/Graphite ferrule onto the capillary
column with the bevelled end facing towards the three-way connector.
c.
Cut 1 cm from the end of the capillary column.
d. Insert the end of the capillary column in the free position of the three-way connector.
e.
Finger-tighten the column retaining nut until it starts to grip the column.
f.
Use the 5 mm wrench to tighten the retaining nut. Use enough pressure necessary to
obtain a good seal.
7. Connect the capillary column to the detector base.
a.
Slide the nut and the graphite ferrule onto the capillary column with the bevelled end
facing the detector base.
b. Be careful to avoid damaging the graphite ferrule when inserting the capillary
column.
c.
Cut 2–3 cm from the end of the capillary column.
d. Insert the capillary column into the detector base body and slide the ferrule up to the
detector base.
e.
Finger-tighten the capillary column retaining nut until it starts to grip the column.
f.
Push the capillary column through the detector base according to the detector in use.
g. Use the 1/4-in. wrench to tighten the retaining nut.
h. Use enough pressure necessary to obtain a good seal without overtighten.
