Operation
With EFC installed there is one additional screen to configure accessed by
pressing the FLOW/PRESSURE key. Type 3 EFC allows the user to set a
constant flow or to program the flow. The status field displays the column
pressure, actual flow and column linear velocity. Note that type 3 actually
sets a required carrier flow into the injector/column system. A leak in the
system would be indicated to the user by a drop in inlet pressure.

The screen above represents a typical application of type 3 EFC with an
isothermal injector. Normally this type of injection system is maintained at
constant flow during the analytical run. However, if required the column flow
rate could be programmed during the run.
