Translating ChemStation Methods

ChemStation Translation Table
Translating ChemStation Methods

The ChemStation (CS) method contains parts of the Chromeleon PGM File, the QNT Method, and the Report Definition File (RDF). Chromeleon uses only the relevant information of a ChemStation method (i.e., Peak Table and Integration Events) to create a new QNT Method with the same name. A message appears if this method already exists. You can either overwrite the old method or cancel the import.

The table below lists the Integration Events of a ChemStation method and the equivalent detection parameters in Chromeleon:

ChemStation	Chromeleon	Comment
Slope Sensitivity	Sensitivity	Translation factor: 20
Peak Width	Peak Slice	Translation factor: 0.8
Area Reject	Minimum Area	Translation factor: 1/60
Height Reject	Minimum Height
Shoulders	Peak Shoulder Threshold	Off = 0ff, On = 0.1
Baseline Now	Lock Baseline	On
Baseline at Valleys	Valley to Valley	Off = Off, On = On
Baseline Hold	Lock Baseline	On = At Current Level, Off = Off
Tail Tangent Skim	-
Tangent Skim Mode	-
Area Sum	Peak Group Start Peak Group End	On Off
Integration	Inhibit Integration	Off = On, On = Off
Negative Peak	Detect Negative Peaks	Off = Off, On = On
Split Peak	-
Fixed Peak Width	Peak Slice
Auto Peak Width	-
Detect Shoulders	Peak Shoulder Threshold	Off = 0ff, On = 0.1
Shoulder Mode	-	-
Solvent Peak	-
Baseline Backwards	-
Baseline Next Valley	-
Unassigned Peaks	-

Chromeleon provides equivalents in the QNT Method for the following peak table parameters of a ChemStation method:

ChemStation	Chromeleon	Comment
Compound	Peak Name
RT	Ret. Time
RT Window Low RT Window High	Window	Calculated from the difference: RT High - RT Low
