4
Place the column into the base of the detector.
5
Thread the capillary column nut and ferrule finger-tight.
6
Gently slide the column into the detector until the mark on the
column aligns with the bottom edge of the column nut.
7
Continue to hold the column as you tighten the nut just enough to
hold the column firmly in place and to create a good seal.
Connect Metal
Packed
Column to
Detector
After conditioning your column and cooling the GC, follow the steps below
to connect your metal packed column to the detector. Note that the
appropriate packed column adapter must be installed.
Hot Surfaces are Exposed.
1
If using a detector other than TCD, locate the packed column
detector adapter in the Packed Column Kit and install on the inlet
to the detector. The TCD inlet is designed for packed column
installation.
2
Insert the open end of the packed column into the detector inlet or
adapter, and push until it reaches a stop.
3
Hold the column in place and finger-tighten the column nut. Then,
with a 7/16
″
wrench, tighten a further 3/4-turn past finger-tight. On
subsequent installations, tighten the nut 1/4 to 1/2-turn past finger-
tight.
Check for
Leaks
Inspect your GC system for leaks before heating. An electronic leak
detector is the most reliable method to check the injector and detector
fittings for carrier gas leaks.
C A U T IO N
Never use soaps, such as Snoop®. These may contaminate the
system and cause permanent damage to capillary columns. If a liquid
leak detector is desired, try a 50/50 mixture of isopropanol/water.
