Need To Look At Files With Data Dependant Experiments?

Though TraceFinder is primarily a quantitation application, it does have some provisions for unknown identification.

Mainly used in Single Quad or Ion Trap Analysis, the qualitative processing allows for scanning files along a TIC for peaks of interest and then eliminating the known targets and performing library searches against the unknown peaks. Also, TF gives the ability to look at the peaks that generate data dependant scans(DDS). It will sum the spectra and compare to a NIST style library.

To utilize this feature you must have two things. One a Method template, with the parameters set for Qualitative processing and DDS enabled, and a Sample Type of either and Unknown/TIC or Unknown Qual.

If you are performing Quantitative processing those will be perfromed first and Qualitative will occurs on the sample after Quan results are created.

If you have Qual resuts in data review you will have a green button to select the QualView.

Follow the the Video in setting up a Method Template and then using it in a Batch to review qualitative results.

If the video is blurry select the cog wheel in the lower right of the video window and adjust the resolution setting.
