Working with Methods
A method contains a complete set of injection, separation and detection parameters,
including the timetable and injector program. Vial range information is not part of
the method.
There are two types of methods:
• The module method. The method parameters are stored in the individual LC
modules and not in the control module. A method that is stored in the individual
LC modules can be loaded, modified, saved and run from the control module.
• The PC card method. The method parameters are stored on a PC card. A method
that is stored on the PC card can be loaded to the LC modules or transferred to
another LC system. Methods cannot be run directly from the PC card. The
method must first be loaded from the PC card before it can be run. When the PC
card method is loaded it becomes a module method.
Unless stated otherwise, the following sections refer to module methods.
Loading a Method
A method can be loaded using the Method button [F3] in the Analysis or Samples
screen:
1 Enter the Analysis or Samples screen.
2 Select Method; the current parameters are displayed.
3 Press the Module button [F1].
4 Select a method from the list.
5 Press the Enter key.
You can also load a method directly from the Analysis screen by using the selection
keys and changing the method in the method list.
The Method/Module screen lists all methods that are stored in the modules. For each
method there is a date when the method was last changed and a short user
description. When a method is loaded it becomes the current method.
A method might be identified as partial method. This means, that there is a
mismatch between the actual and the original system configuration, for example
