Cannot Set a Flow or Pressure
If you cannot set a flow or pressure using the split/splitless,
MMI, 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.
• Check that the flow is turned on.
• Check the inlet mode. When using inlet flow control, you can
set only flow control modes for columns. When using inlet
pressure control, you can set the column for both flow and
pressure modes.
