4 GC Not Ready Symptoms
A Gas Does Not Reach Setpoint Pressure or Flow
If an inlet does not reach its pressure setpoint, it will shut down
in an amount of time determined by the type of inlet. Do the
following:
• Check for sufficient gas supply delivery pressure. The
pressure at the supply should be at least 10 psi greater than
the desired setpoint.
• Check for leaks. (See “Checking for Leaks” .)
• If using gas saver, be sure that the gas saver flow rate is high
enough to maintain the highest column-head pressure used
during a run.
• Check for an incorrectly installed column.
If you are using a split/splitless inlet, PTV inlet, or volatiles
interface:
• Check the split ratio. Increase the amount of split flow.
