Intelligent reflex targeted reinjection workflow for pesticide screening in food matrices

29 Jul 2024

Robust and reliable screening methods for pesticide analysis in food matrices are a continuous point of challenge with the growing number of matrix samples, varying detection limits, and a continuously expanding list of emerging contaminants. Data-independent acquisition (DIA) methods allow users to simultaneously screen for targets of interest while also evaluating valuable information on unknown compounds. Agilent Technologies demonstrates a DIA methodology for the screening of pesticides in a complex matrix with the Agilent Revident Q-TOF LC/MS. Plus, discover how intelligent reflex automated targeted reinjection has been used for the acquisition of compounds screened as present or questionable.

Revident quadrupole time-of-flight LC/MS (LC/Q-TOF)

Agilent Technologies

To stay competitive and adjust to changing industry requirements, you need evolved instrumentation with complete workflow solutions to meet current and future challenges. You must ensure that your lab can respond to emerging and unexpected contaminants with broader screening and retrospective analysis. The Agilent Revident LC/Q-TOF answers these challenges by maximizing time and productivity with sophisticated instrument intelligence.
