(1)  An eluent is fed by the pump through the degasser.

(2)  A sample is injected from the autosampler.

(3)  The injected sample is separated through the column which

is maintained at a constant temperature by the column
oven.

(4) Each component separated from the sample is then

detected as a signal by the detector.
