860 pesticides in one database: screening, validation and quantification in one run
UHPLC-QTOF workflow with full scan and bbCID interlace and TASQ processing
Ready-made UHR-QTOF workflow for simultaneous screening, validation and quantification of pesticides.
PesticideScreener 2.0 combines UHPLC-QTOF, full-scan and bbCID data, pesticide database and TASQ processing. The approach allows hundreds of compounds to be tested in one run, reduces the risk of false-positive results, and reanalyzes stored data as the database expands.
The official validation poster lists a base of approximately 860 pesticides and a range of m/z 30–1000. For a representative set of 272 pesticides, the criteria for mass accuracy of at least 5 ppm or 1 mDa below m/z 200, the deviation of retention time not exceeding 0.1 minutes and the ratio of qualifier ions not exceeding 30% were applied.

Validation results
272 pesticides in salad and orange
One run is the whole list.
- Alternating the full scan and bbCID fragmentation gives data on all ions of the sample
- A database of approximately 860 pesticides and treatment in TASQ
- The saved data is re-checked when the database is expanded
Trustworthy identification
- Criteria: mass accuracy less than 5 ppm (less than 1 mDa below m/z 200), deviation of retention time not more than 0.1 min
- Qualifier-ion ratio – an indicative criterion of not more than 30%
- Calibration by clusters of sodium formate in each run and internal lock mass
Confirmed results
- In independent validation, most of the 272 pesticides met EU SANTE criteria.
- Validated LOQ of 10 μg/kg for most analytes
- Linear calibrations 1–50 ng/mL (r2 > 0.98)
