Cannot Maintain a Pressure as Low as the Setpoint on a Split Inlet
If the GC cannot maintain a pressure as low as the setpoint,
check for the following:
• Consider using a liner designed for split analysis.
• Check for a plugged liner.
• Check for contamination in the split vent line. Contact
Agilent service to replace, if necessary.
• For the split/splitless inlet, replace gold seal.
