Maintaining the COC Inlet 7
Maintaining Your GC 131
• If you are using a cooling tower, grasp the three rings and
unscrew. The spring and duckbill septum may pop out of
the inlet when you remove the cooling tower. Be careful
not to lose them. If they do not pop out, use a thin wire to
remove them from the inlet. Insert the replacement
duckbill septum into the spring and place in the inlet.
Reattach the cooling tower assembly, then finger-tighten.
4 Before making an injection, check the alignment of the entire
assembly using the proper size syringe.
5 Restore the analytical method.
6 Reset the septum EMF counter. See To Reset an EMF Counter
in the Operation Manual.
