This Tuesday morning session will be presided over by Mary Ellen McNally of DuPont Crop Protection (Wilmington, Delaware.
The session will begin with a presentation by Olujide T. Akinbo of Butler University (Indianapolis, Indiana) titled “Development and Application of a Method for the Simultaneous Analysis of Five Bisphenols in Canned Beverages by Solid-Phase Extraction Liquid Chromatography–Tandem Mass Spectrometry (SPE–LC–MS/MS).
He is followed by Dongting Liu of Dow AgroSciences (Indianapolis, Indiana) who will present “The Characterization of Pesticide Soil Metabolites using Microbial Cultures Coupled with Linear Ion Trap Mass Spectrometry”.
Ruipu Mu of Missouri University of Science and Technology (Rolla, Missouri) will present the next talk titled “A Fast Separation and Quantification Method for Nitroquanidine and 2,4-Dinitoanisole by Liquid Chromatography/Tandem Mass Spectrometry”.
Lane Sander of the National Institute of Standards and Technology (Gaithersburg, Maryland) will present “Use of Isotope Dilution Mass Spectrometry Methods in the Certification of Food and Dietary Supplement Standard Reference Materials”.
A 15-minute recess will ensue followed by a talk at 9:35 am titled “The Promise of Dilute-and-Shoot Injections for Pesticide Residue Analysis in Different Food Types Using Experimentally Determined Matrix Effects”. This will be given by Richard Lake of Restek Corporation (Bellefonte, Pennsylvania).
The next presentation is by Rachadaprn Seemamahannop from the University of Missouri, He will talk on the “Evaluation of Oligolysines and Alpah Hydroxyl Acid Capped Oligolysines as Selective Substrate for Rapid Quantification of Trypsin Inhibitor in Food and Feed Formulation with Electrospray Mass Spectrometry (ESI-MS).

Analytical Challenges in Measuring Migration from Food Contact Materials
November 2nd 2015Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
FDA Talks to LCGC About Chromatographic Techniques for PFAS Detection in Food Supply
December 5th 2023A new study details the US Food and Drug Administration (FDA)’s recent expansion to 30 analytes, from a previous 16, in the method for determining per- and polyfluoroalkyl substances (PFAS) in the US food supply, which, in turn, may mean that additional analytes may still yet be identified (1).
