Preventive Maintenance

Split/splitless capillary inlets

CUse 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.

CIf 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.
