This line is the title bar.
It is displayed when Constant Flow is selected in
Flow Mode. Enter a column flow for the analytical
column.
It is displayed when Constant Pressure is selected
in Flow Mode. Enter inlet pressure for the
analytical run.
Set the operating mode required.
Selecting Constant Flow, the column flow is kept
constant throughout the analysis. The pressure at the
column head will change with the column
temperature to maintain a consistent flow.
Selecting Constant Pressure, the pressure at the
column head is kept constant throughout the
analysis. During a temperature program, the column
flow decrease due to the increase of the carrier gas
viscosity.
