• Delete —Click this button to enable the gradient point
delete mode. When this mode is active, PeakTrak will
delete the point nearest the next click on the gradient
curve. Click the Delete button once for each point that
must be deleted from the plot area.
• Run Length — Type or select the length of the run.
Note that 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 minutes or COLUMN VOLUMES
[ON-LINE] (CV). You can configure PeakTrak’s default Run
Length units by changing the CONFIGURATION [4.3.10]
settings.
• Solvent A — Select the desired solvent from the list.
The available solvents are those defined by the
CONFIGURATION [4.3.10] settings.
• Solvent B — Select the desired solvent from the list.
You can program mid-run solvent B changes by clicking
the Edit Gradient button to open the GRADIENT TABLE.
• Edit Gradient — 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
GRADIENT TABLE.
For complete instructions on defining gradient curves, see
DEFINING A GRADIENT [4.4.5].
Gradient Table The gradient table depicts the points that
define the gradient curve in a tabular format. From this table
you can change the duration and %B concentration of any
point on the curve. To do so, select new values for the gradient
points. 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 Gradient Button for the action you desire.
