plot area.
• D
ELETE
—Click this button to enable the gradient point
delete mode. When this mode is active, the system will
delete the point nearest the next click on the gradient
curve. Click the D
ELETE
button once for each point that
must be deleted from the plot area.
• Run Length — Type or select the length of the run.
Note
This will change the scale of the X-axis on the gradient. Points
that define the gradient will be automatically scaled to fit the
new run length. The run length can be expressed in.
• Solvents A and B— Select the desired solvent from the
list. The available solvents are those defined by the
C
ONFIGURATION
settings. You can program mid-run
solvent B changes by clicking the E

G
RADIENT
— Although the gradient may be edited
directly within the plot area, you can also edit the
gradient in tabular form. Click this button to open the
G

. The G
RADIENT
T
ABLE
also lets you
program solvent changes in the gradient.
• 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
deleting rows in the table. To change the number of
points, first highlight a table cell or row. Then click the
appropriate G
RADIENT
button for the action you desire.
• Insert Point — This command or button will insert a row
below the selected point.
• Delete Point — This command will delete the selected
row. You cannot delete the initial point. There must be
at least two points to define a gradient. The system
automatically updates the Run Length setting or scales
the other points when you change the number of points
and their duration on the curve. To close the G
RADIENT
T
