Shoulder (front, rear)
Shoulders occur when two peaks elute so close together that no valley exists
between them, and they are unresolved. Shoulders may occur on the leading
edge (front) of the peak, or on the trailing edge (rear) of the peak. When
shoulders are detected, they may be integrated either by tangent skim or by
drop-lines.
Slope
The slope of a peak, which denotes the change of concentration of the
component against time, is used to determine the onset of a peak, the peak
apex, and the end of the peak.
