Entering Settings
Entering Settings
To set up the gradient analysis you will set the LC system settings to default
and then modify selected settings, the other settings will remain with their
default values. You will then save these settings to a method called GRAD.
To set up the solvent gradient, you will create a timetable in the method. This
is done using the Timetable screen, accessed by selecting the Timetable button
[F2] in the Pump settings screen.
The example assumes that the Timetable is empty. If the Timetable is not
empty, use the All Lines item, accessed by pressing the Delete button.
