Understanding Methods
When you set the detector to Method Mode, the default main screen is the Method Screen.
The first time you start the detector in Method Mode, the detector displays the default
method. This method has no method number or name, and it is not stored, as shown in the
figure below.
A method is a set of stored parameters for a specific sample. For example, a method allows
you to automatically change a wavelength, for specific durations, during a chromatogram.
Once you store a method, you can recall it and run it. You can run an active method. The
active method is the method that is currently running on the Series 200 UV/VIS LC Detec-
tor, or the method currently shown on the display.
There are three possible states for a method:
• Default state
The method has no method number or name. This is the state of the method that appears
when you first turn on the detector.
• Current state
This is the active method that appears on the display. The method status changes when
you edit the method. The changes are not saved unless you store the method.
• Stored state
The method is saved. It has a method number and name. A stored method can be
recalled.
