New TF 3.0 Targeted Screening Workflow in Data Review (or the marriage of TF and ExactFinder)

A new feature to TraceFinder 3.0 is targeted screening. The workflow and method setup that were included in ExactFinder has been included in TraceFinder 3.0. Though it has been expanded to support Nominal Mass as well as HRAM.

That means this feature will work for all mass spectrometers from the GC single quads to the Q-Exactive.

Though some sections are more geared for HRAM, they can just not be used when using nominal mass data.

The other aspect is that TF gives you the ability to acquire, process and report on the fly during acquisition. Therefore, if you so choose you don’t have to wait to review your data. So this expands the capabilities that was introduced in ExactFinder.

This is our first step with this functionality and more is to come in following releases, but there are some interesting things that can be done by having these two workflows combined.

Again the video is a little longer that my 2 minute rule but there is a lot to look forward to.
