sample injected. This run is stored and subtracted from the real run to produce
a flat baseline. Figure 26 illustrates the concept.
All conditions must be identical in the column compensation run and the real
run. The same detector and column must be used, operating under the same
temperature and gas flow conditions. Two baseline profiles may be stored (as
[Col Comp 1] and [Col Comp 2]).
