Tuesday Morning Session on Chiral Separations
Terry Berger of Berger Instruments (Newark, Delaware) and Geoffrey Cox of Chiral Technologies, Inc. (West Chester, Pennsylvania) will chair a Monday morning session titled "Chiral Separations" in Ballroom B.
Terry Berger of Berger Instruments (Newark, Delaware) and Geoffrey Cox of Chiral Technologies, Inc. (West Chester, Pennsylvania) will chair a Monday morning session titled “Chiral Separations” in Ballroom B.
The session’s first presentation will be given by Wolfgang Lindner of the University of Vienna (Vienna, Austria). The title of Linder’s presentation is “The Potential of Novel Zwitterionic Chiral Ion Exchanger for HPLC Enantiomer Separations of Charged Analytes.”
Lindner’s presentation will be followed by a study presented by Kenji Hamase of Kyushu University (Fukuoka, Japan). Hamase’s presentation is titled “Two-Dimensional HPLC Determination of All Proteinogenic Amino Acid Enantiomers in Mammalian Tissues and Physiological Fluids.”
The final talk in this Monday session is titled “Chiral Gradient Elution Separations: Modeling of Normal and Reversed-Phase Systems and Prediction of Resolution for Complex Mixtures.” It will be presented by Session Co-Chair Geoffrey B. Cox.
Following Cox’s presentation, attendees are invited to Exhibit Hall A&B for a light breakfast and snacks.
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).
