Maintaining the Instrument
User Information 147
After maintenance or repair, leaks are most often found where
fittings were disconnected and reconnected. These areas
include:
• Transfer line connections to the inlet such as needle and
septum, zero dead volume union, and volatiles inlet.
• Connections to the 6-port sampling valve.
• Zero dead volume union above the sampling probe.
In some applications, residues and aggressive solvents can
cause damage to the 6-port valve and restrictions in the vent
tube and solenoid vent valve.
