Carefully screw the jet into the housing. Tighten 1/6- turn
past finger- tight (1/6- turn is one “flat” on a typical
screwdriver handle, or the jet head).
10 Install the collector assembly. (See “To Replace the FID
Collector Assembly” on page 209.)
11 Reset the jet counter. See To Reset an EMF Counter in
the Operation Manual.
12 Attach the capillary column to the detector.
a Install the column in the detector. (See “To Install a
Capillary Column in the FID” on page 205.)
b After the column is installed at both inlet and detector,
establish a flow of carrier gas and purge as
recommended by the column manufacturer.
c Check the FID leakage current. (See “To Check the FID
Leakage Current” on page 224.)
d Bakeout the detector. (See “To Bakeout the FID” on
page 229.)
e Restore the analytical method.
Do not overtighten the jet! Overtightening may permanently deform
and damage the jet, the detector base, or both. The torque
specification is 10 inch-pounds.
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.
