In TF Methods Ion Ratios can be set but updated not to calculate if needed.

In this case the user may find that they have set up a sort of generic method with two confirming ions.

The body they are doing the work for requires only one as part of their data set.

The user can simply go to the method and select an ion and disable the calcualtion by unchecking the “Enable” box on the ratios page.

The ratio wont be calcualted and the chromatogram will not be displayed in data review or on reports.
