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.

method files ( *.mtw ) in the Methods directory. 35
prepared, write-protected methods are copied to this directory at pro-
gram installation.
Each system is linked to a method. This method is called
