Gradient Preview Functionality

The gradient preview provides the following functions:
•
•
•
•
Reference Signal
The user can load a chromatographic signal from an LC detector - a so-called
reference signal. The signal will be shown in the gradient preview. This signal is
automatically shown in the gradient preview of the setup dialog as long as the
reference signal is part of the method. The signal can also be removed from the
method or replaced by another signal.
Loading / removing a reference signal is triggered by toolbar buttons (or the
context menu) of the gradient preview.
