4.4 Methods

A method contains all information necessary for data acquisition, in-

tegration, peak evaluation and quantification. It can be considered

as the chromatogram template, i.e. chromatogram without raw data.
Methods are stored as method files (

) in the

Methods

directory.

Each system is linked to a method. This method is called processing

method and is opened automatically at the start of a new determina-

tion.
