The high split seal should not be used with the
recommended Agilent glass split liner (part
number 5183-4647) or if the inlet is being used
in splitless mode. After any system modifica-

user information.
Cannot achieve setpoint pressure
The purpose of this section is to outline a logical
procedure for troubleshooting a 6850 series GC
that will not equilibrate to the setpoint pressure
of the capillary inlet system. The inlet actual

The procedures in this document address the
class of problems that are generally related to
inlet leaks.
Refer to this schematic of the capillary inlet for
the following troubleshooting procedures:
