Gradient Table The gradient table depicts the points that
define the gradient curve in a tabular format. From this table
you can change Solvent B (Rf+ systems, including those
equipped with 4x), the duration, and %B concentration of any
point on the curve. To do so, select the new value for a gradient
point. Changes that you make to the table will be reflected in
the gradient plot area.
You can also change the number of points on the curve by
