To Attach the Transfer Line to a Split Splitless or Multimode Inlet
1 Gather the following:
• Lint- free gloves
• Two 7- mm wrenches
• Capillary column cutter (5181- 8836)
• Inlet septum, green (5183- 4759)
2 Cool the GC inlet to a safe handling temperature.
3 Cool the GC oven to room temperature to prevent column
damage. Then turn off the carrier gas.
4 Install the transfer line to the 6 port valve. See “To Install
a Fused Silica Column into the Transfer Line”.
5 Slide the one- piece septum nut and strain relief coupling
onto the tubing until the inner metal sleeve of the
transfer line bottoms- out on the strain relief.
6 Slide the septum onto the tubing until the septum is
against the bottom of the one- piece septum nut and
strain relief coupling.
7 Trim the tubing 35 mm past the end of the septum.
8 Install the inlet liner (with o- ring) that is appropriate for
your application.
9 Insert the tip of the transfer line into the inlet.
10 Finger- tighten the strain relief coupling.
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
Be careful! The oven and/or inlet may be hot enough to cause
burns. If either is hot, wear heat-resistant gloves to protect your
hands.
