Cannot Set a Flow or Pressure
If you cannot set a flow or pressure using the split/splitless,
PTV, VI, or cool on-column inlets, do the following:
• Check the column mode.
• Check that a capillary column is configured to the correct
inlet.
• Check the configured column dimensions.
• Check that the flow is turned on.
If you cannot set a flow or pressure using the purged packed
inlet, do the following:
• Check the column mode. The packed inlet uses flow control
for undefined columns.
• Check that the flow is turned on.
