Aroma and Metabolic Profiling of Hass Avocado via HS-SPME-GC-MS
Researchers at the University of Caldas (Manizales, Caldas, Columbia) investigated the volatile organic compounds comprising the volatilome of Hass avocado peel, pulp, and seed grown in the northern Caldas (as well as avocados purchased from commercial sources), employing headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC–MS) for their extraction and identification.
Paraben Exposure and Childhood Obesity Risk in Preschoolers: UPLC-MS/MS Insights from Recent Study
Researchers speculating that exposure to paraben in early childhood is associated with changes in satiety hormones performed analysis of urinary methyl, ethyl, propyl, and butylparaben (MeP, EtP, PrP, BuP) levels in 4–6-year-old children, using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).
Mass Spectrometry Fingerprinting and Neural Networks for Coffee Sensory Profiling
Researchers from the University of Campinas (Campinas, Brazil) and the Waters Research Center (Budapest, Hungary) introduced a rapid, automated method using laser-assisted rapid evaporative ionization mass spectrometry (LA-REIMS) with high-resolution mass spectrometry to fingerprint coffee samples and predict sensory properties. LCGC International spoke to Leandro Wang Hantao of the University of Campinas regarding their work and the paper that resulted from it.
Research conducted by the University of Florida and the University of California used targeted metabolomics in pomegranates to profile essential primary and secondary metabolites, including organic acids, amino acids, sugars, hormones, and phenolic compounds, using gas chromatography mass spectrometry (GC-MS) and liquid chromatography mass spectrometry (LC-MS).

Sustainable Materials in Chromatography: Faster Analyses, Less Consumption
July 10th 2025Harry Ritchie, PhD, Director of Business and Market Development at Advanced Materials Technology, shares how crucial sustainability has become in the field of chromatography, and provides helpful advice for labs looking to meet sustainability initiatives.
HPLC Phytochemical Profiling of Residual Artichoke Leaves
In a new study, researchers from the University of Milan used high-performance liquid chromatography (HPLC) to phytochemically profile residual leaves of Carciofo di Malegno, a traditional Italian artichoke variety.
GC-MS Sheds Light on Chemical Communication Between Desert Locusts
A multinational research team used behavioral assays and gas chromatography-mass spectrometry (GC-MS) to examine short- and long-term interactions between juvenile and adult desert locusts to test their hypothesis that cross-stage interactions influence juvenile cohesion and physiological traits.
Navigating the Impact of Funding Cuts: Voices from the Research Community
Shifts in U.S. federal science funding—driven by the newly established Department of Government Efficiency (DOGE)—are causing delays, uncertainty, and program changes across academic and regulatory research institutions.
