The TSQ 8000 system allows you to set up a full scan
acquisition throughout the duration of your MRM
analysis. Each acquisition will then have full scan data to
identify non-target compounds, in addition to MRM data
to confirm and quantitate the target list. This mode of
analysis is facilitated with the TraceFinder EFS software
qualitative processing view within its standard
quantitative batch analysis, which automatically detects,
identifies, and reports non-target compounds (Figure 7).
General Unknown Screening
Another limitation of the classic MRM approach to
pesticide analysis is that, due to its targeted nature, if a
compound is not part of your target list, you are not going
to find it, even if it is present in large quantities in your
sample. This limitation is removed with capability of the
TSQ 8000 system to perform simultaneous full scan/
MRM.
Figure 7. Qualitative view of TraceFinder EFS software for analyzing fruit juice with simultaneous full scan/Timed-SRM on the TSQ 8000 system. In addition to
quantitating and confirming the 158 target compounds by MRM (top), TraceFinder EFS software has identified three high-level unknowns by full scan analysis
(bottom): 2,4-bis(1,1-dimethylethyl)-phenol, triethyl citrate, and Vitamin E.
