From Screening to Confirmation: A Comprehensive Food Safety Analysis from Initial DIA Screening to Automatic Reinjection for Suspect Confirmation

This event is now available on demand.

Event Overview:

The new Revident LC/Q-TOF system is leveraged for the screening of pesticides in complex matrix utilizing data independent acquisition (DIA). DIA allows for retroactive analysis of an ever-growing list of emerging contaminants. 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. The combination of screening and automated targeted reinjection reduces the amount of time from sample introduction to confident characterization.

Key Learning Objectives:
  • Gain an introduction to the new Revident LC/Q-TOF
  • Learn how data independent acquisition (DIA) and the LC Screener Tool allow for easy and simple screening of pesticides in complex matrix with confidence.
  • Understand how the ability to confirm identified and tentatively identified compounds through automatic reinjection reduce complete analysis time and manual reinjection decisions.
Who Should Attend:
  • Lab manager in Food safety and environmental labs
  • Principle Investigators in Food safety and environmental research

LC/Q-TOF Marketing Product Manager
Agilent Technologies
After finishing his MSc in Chemistry at Wuerzburg, Germany, Christain Klein moved to the Max-Planck-Institute for Biochemistry in Martinsried, Germany. The title of his Ph.D. thesis (2005), conducted in the Oesterhelt group, was “Proteome analyses of Halobacterium salinarum” and included MALDI and ESI mass spectrometry, as well as 2-dimensional gel-electrophoresis, with a general focus on membrane proteins. In 2006, he went as a PostDoc to Ghent, Belgium to study the separation of membrane proteins via diagonal chromatography with Joel Vandekerckhove. He then returned to the Max-Planck-Institute, working on separation and identification methods for small proteins, before joining the corporate environment in 2007 as a demo chemist with a focus on proteomics applications. In 2010, he joined the R&D team with Agilent, working on LC/MS Q-TOF systems including ion mobility. Since 2018, he is the LC/Q-TOF and IM-QTOF Product Manager.
