Split/splitless capillary inlets

Use leak detection fluid to check for leakage at the column nut. If
leakage is observed, try tightening the nut first. If leakage continues,
replace the ferrule.
Note that if the inlet is hot, leak detection fluid may boil, giving false
indication of a leak.
If the septum and column nut prove to be leak•free,replace the seal
(O•ring)on the inlet insert.
Repressurize the system and check again for overall system
leak•down.
