A Walkthrough Food Safety Analysis from Initial DIA Screening to Automatic Reinjection for Suspect Confirmation

The new Revident LC/Q-TOF system is leveraged for the screening of pesticides in complex matrix utilizing data independent acquisition (DIA). Confident identification is made through a combination of high-resolution, extended dynamic range, stable accurate mass, and isotopic fidelity which can be quickly and easily analyzed via the customizable LC Screener Tool, simplifying the processing of complex screening data. Along with this screening capability, new automated software, Intelligent Reflex, uses the results and allows for the reinjection and targeted confirmation of questionable and/or identified residues. This reduces the amount of time from sample introduction to confident characterization.
