This Tuesday morning session will be presided over by Alison Danell of East Carolina University, and it will be held at 8:30–10:30 a.m. in Exhibit Hall AB.
The first presentation in the session will be delivered by Zhenzhen Wang of Michigan State University (East Lansing, Michigan) and is titled “Probing Dynamics of Plant Specialized Metabolism Through Stable Isotopic Labeling and Nonselective Collision-Induced Dissociation.”
Wang’s presentation will be followed by a talk to be given by Kristyn Roscioli of the Environmental Molecular Sciences Laboratory, PNNL (Richland, Washington) titled “Characterizing Chemical Composition of SOM Using Graduated Extractions, Deep Fractionation and LCMS to Detect/Quantify a Broad Range of Compounds.”
Next, Takayuki Kawai of the University of Illinois at Urbana-Champaign (Urbana-Champaign, Illinois) will present a talk titled “Analysis of Enantiomeric Amino Acids in Biological Samples Via Capillary Electrophoresis Coupled with Mass Spectrometry.”
Matthew Crowe of Dow Chemical Company (Collegeville, Pennsylvania) will next present “Characterization of Alkylpolyglucoside Surfactants with Liquid Chromatography/Mass Spectrometry and Evaporative Light Scattering Detection: Total Characterization without a Reference Standard.”
The next presentation will be given by Qian Ruan of the Department of Biotransformation, Bristol-Myers Squibb (Princeton, New Jersey) and will be titled “Application of Qualitative and Quantitative Analysis of HRMS to Fast Identification of Major Drug Metabolic Pathways and Drug-Metabolizing Enzymes.”
The final presentation in the session will be delivered by David Siegel of the University of Groningen (Groningen, The Netherlands). His presentation is titled “Combining Derivatization and SWATH for the Integrated Quantification and Identification of Aldehydes and Ketones in Biological Samples.”
Linking LC-HRMS Features to Aquatic Toxicity: A Nontargeted Approach Without Compound Identification
July 7th 2025A recent study conducted by the University of Amsterdam (Amsterdam, Netherlands) and the University of Queensland (Queensland, Australia) developed a novel prioritization strategy that directly links fragmentation and chromatographic data to aquatic toxicity categories, bypassing the need for identification of individual compounds. LCGC International spoke to Viktoriia Turkina of the University of Amsterdam, lead author of the paper that resulted from this study, about their work.
Detection and Risk Assessment of Mycotoxins in Commercial Tortillas Using HPLC-Based Methods
July 4th 2025A joint study between Selçuk University (Konya, Turkey) and Hitit University (Corum, Turkey) determined the natural occurrence and concentrations of the mycotoxins ochratoxin A (OTA) and deoxynivalenol (DON) in commercially available tortillas in Turkey. Contamination levels were quantified using validated analytical methods based on high-performance liquid chromatography (HPLC) coupled with fluorescence or ultraviolet detectors (HPLC-FLD or HPLC–UV).
