Enable/Disable Ion Ratio

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.

The Sum of All Peaks

One of the key features of TF is the use of a compound being composed of multiple components.

So the gist, of it is that a specified compound can consist of up to 6 quantitative peaks, each of those can have up to 10 confirming ion ratio peaks.

So A compound can consist of up to 66 chromatographic peaks when using mass spectral data.

This means that you can visualize under the compound name quantitative peaks and their associated ion ratio confirming ions.

 

The compound is composed of these multiple peaks, which have summed areas. But they can be visualized separately. The total response of adding all the, lets say peak areas, is the total response of the compound. And by using the multiple quan peak feature, these chromatographic peaks don’t have to be at the same retention time. So if you were doing a chiral separation but wanted the total response, you would just make them individual quan peaks under the compound.

 

Now if you have coeluting peaks and want one big peak to represent your compound, then you can use the signal pane’s mass grid to accomplich this type of mass intergration.

All the responses are summed, but no individual visualizations.
