At the Asilomar Conference for Mass Spectrometry in Food Safety and Quality, Bruker today launches the high performance, accurate mass-based PesticideScreener™ solution for multi-residue analysis as a turnkey approach to accurate and verifiable analysis of pesticides in food and feed. PesticideScreener is based on full-scan high resolution accurate mass data for multi-target screening, confirmation and quantitation to deliver confident and comprehensive multi-target analysis of pesticides in food in a single LC-MS run.

(Photo: Business Wire)Enabling fast and reliable identification of selected compounds at ppb levels in complex sample matrices, with very low false positive rates, PesticideScreener identifies compounds based on combined scoring of mass accuracy, isotopic patterns, retention times and, optionally, MS/MS qualifier ion fragment data. At the heart of the PesticideScreener is a high-quality database of over 700 target pesticides. This database is not merely a “list of compounds” but includes:
- Retention times for the matched UHPLC method
- Adduct information
- Isomer information
- Fragment ion information
- Isotopic confirmation
- Qualifier ions for “one-shot”-confirmation in broad-band MS/MS mode
- High resolution AND high speed simultaneously for coupling to UHPLC
- Unique Full Sensitivity Resolution (FSR) of greater than 40,000
- One shot method, providing screening and confirmation in the same run
- Excellent sensitivity, high dynamic range and mass accuracy, meeting the performance requirements established in EU protocol SANCO/12495/2011
- True Isotope Pattern (TIP) for ultimate confidence in molecular formula determination
- High-resolution extracted ion chromatograms (hrXIC) at +/- 1 mDa.
