• For complete instructions on defining gradient curves,
see Section 5.3.3 Defining a Gradient. The gradient
table depicts the points that define the gradient curve in
a tabular format. From this table you can change
Solvent, 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 inserting or
