In the second section of our interview with Jennifer Geddes-McAlister of the University of Guelph, winner of the ASMS 2025 Diversity, Equity, Inclusion and Accessibility (DEIA) Mentorship Award, she discusses her hopes for the upcoming ASMS 2025 conference in Baltimore.

Gas chromatography–mass spectrometry (GC–MS) was used to detect the chemical components of natural musk, harvested from forest musk deer at multiple stages of maturity. This research combines metabolomic profiling with biosynthetic pathway analysis to identify potential precursors and enzymes involved in musk biosynthesis.

Researchers at Baylor College of Medicine’s Children's Nutrition Research Center (Houston, Texas) developed and validated a high-throughput extraction and ultrahigh-performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) method to separate and quantify 39 spinach flavonoid species in 11.5 min.

Two proof-of-concept hydrophilic interaction chromatography HILIC) methods were developed in a joint study conducted by the University of Geneva (Switzerland), Sanofi, and the Waters Corporation—one for disrupting LNPs and retaining the mRNA, and another for detecting only unencapsulated mRNA to assess encapsulation efficiency. LCGC International spoke to Jonathan Maurer, first author of the paper that resulted from this study, about the methods and the efforts that led up to their development.

A joint study between the University of Tennessee (Knoxville, Tennessee) and the University of Pennsylvania School of Veterinary Medicine (Philadelphia, Pennsylvania) compared directly measured vitamin K1 (vitK1) concentrations in healthy dogs and dogs with chronic enteropathy (CE) using liquid chromatography tandem mass spectrometry (LC–MS/MS); they also investigated whether supplementation of vitK1 in dogs with CE would significantly increase vitK1 concentrations.

A study by researchers from Bonn-Rhein-Sieg University of Applied Sciences and the University of Duisburg-Essen reported on the development of a GC–IMS method for the detection of nine N-nitrosamines in drinking water.

A study conducted by the Agriculture Research Centre of Giza, Egypt, and Jilin Agricultural University in China, evaluated the efficacy of stinging nettle extract, nettle smoke, and formic acid in the controlling of Varroa mites, a major threat to honeybee colonies, with a focus on mite infestation reduction, honeybee mortality, and biochemical responses. Gas chromatography–mass spectrometry (GC–MS) was used to identify key bioactive compounds in the stinging nettle extract.

Peter Boler, Vice President of Marketing at VUV Analytics, explains the importance of vacuum ultraviolet (VUV) detection and new technology that has emerged to support this methodology.

Based on their hypothesis that smelling anxiety chemosignals can, like visual anxiety induction, lead to an increase in odor sensitivity, a joint study between the University of Erlangen-Nuremberg (Erlangen, Germany) and the Fraunhofer Institute for Process Engineering and Packaging (Freising, Germany) combined behavioral experiments, odor profile analysis by a trained panel, and instrumental analysis of odorants (gas chromatography-olfactometry) and volatiles (gas chromatography-mass spectrometry).

Scientists from the University of Santiago de Compostela developed a liquid chromatography quadrupole time-of-flight mass spectrometry (LC–QTOF-MS) operated in data-independent acquisition (DIA) mode for pesticide quantification in agriculturally impacted waters.

A pilot study investigating whether nicotinamide adenine dinucleotide kinase (NADK) expression is selectively diminished in alcohol-associated liver cirrhosis (AC), as well as evaluating its potential as a biomarker for this condition, measured AC and non-AC (NAC). Nicotinamide adenine dinucleotide (NAD+) and nicotinamide adenine dinucleotide phosphate (NADP+) levels in human liver samples were measured using liquid chromatography-mass spectrometry (LC-MS).

A joint study between the University of Oklahoma Health Sciences Center (Oklahoma City, Oklahoma) and the UC Davis West Coast Metabolomics Center (Davis, California) identified differentially regulated lipids in type 2 diabetes (T2D) and obesity through the application of reversed-phase liquid chromatography-accurate mass tandem mass spectrometry (RP-LC-accurate MS/MS).
