Note Could be necessary to adjust the position of the Tee connector when installing
backflush line, precolumn, and column to stress as minimal as possible.
1. Connect the backflush line metal tube coming from the bottom of the SSLBKF injector
module or PTVBKF injector module to the Tee connector.
Tip The backflush line must be bent as required by the position of the Tee connector
on the mounting bracket.
a. Slide the retaining nut and the ferrule onto the end of the backflush line.
b. Insert the backflush line into the Tee connector.
c. Finger-tighten the retaining nut until it starts to grip the backflush line.
d. Use the 5 mm wrench to tighten the retaining nut. Use enough pressure necessary to
obtain a good seal without overtighten.
2. Connect the precolumn to the Tee connector.
Note Always use original Thermo Fisher Scientific precolumns.
The use of precolumns not meeting the specifications of our products does not ensure
a good operation of the instrument and may even compromise the analytical results.
Thermo Fisher Scientific precolumn (2 m; 10 m) are mounted on the appropriate
rack and identified with a relevant label fixed on the rack.
a. Place the precolumn on the column support.
b. Slide the retaining nut and the 0.8 mm Vespel/graphite ferrule onto the precolumn
with the flat end facing towards the Tee connector. Be careful to avoid damaging the
graphite ferrule when inserting the precolumn. Always use a new ferrule of the
correct diameter.
c. Cut 1 cm from the precolumn end.
d. Insert the precolumn into the Tee connector in the side with the dot that it must be
normally be turned towards the ceiling of the GC oven.
e. Finger-tighten the precolumn retaining nut until it starts to grip the precolumn.
f. Use the 1/4-in. wrench to tighten the retaining nut. Use enough pressure necessary to
obtain a good seal without overtighten.
3. Connect the precolumn to the injector base.
a. Slide the retaining nut and the graphite ferrule onto the fused silica precolumn (0.53
mm ID; 2 m length) with the beveled 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 about 3 cm into the bottom of the injector.
