Cinnamon and its byproducts have been used for many years because of their antidiabetic effect. In a joint study conducted by Gazi University (Ankara, Turkey) and Düzce University (Düzce, Turkey), high performance liquid chromatographic (HPLC) and thin-layer chromatography (TLC) analyses, macroscopic analyses, and enzyme inhibition assays on diabetes-related enzymes were performed on cinnamon samples to determine whether they are safe to use for health purposes.

As the organic tea industry grows, verifying its authenticity is essential for maintaining market stability. A recent study proposed a model for distinguishing organic tea from conventional varieties, with components (water extract, polyphenols, mineral element) of each type compared through high performance liquid chromatography (HPLC), inductively coupled plasma–mass spectrometry (ICP-MS), and mass spectrometry (MS) analysis.

A study conducted at Henan University of Science and Technology (Luoyang, China).aimed to characterize the pharmacokinetic profiles of milbemycin oxime in Pekingese dogs following a single oral (PO) and intravenous (IV) dose. Blood samples were collected at various time points, with milbemycin oxime concentrations measured using a validated high performance liquid chromatography (HPLC) method with ultraviolet (UV) detection.

Emanuela Gionfriddo and Madison Williams from University at Buffalo, the State University of New York, NY, USA discuss the important role that solid-phase microextraction (SPME) techniques with gas chromatography mass spectrometry (GC–MS) can play in the analysis of per- and polyfluoroalkyl substances (PFAS).

Research on plastics in aquatic environments is well-established, but little is known about their presence, pathways, and effects in soil ecosystems. The iMulch project aims to address this need as well as the growing concern of plastic pollution in soils. Focusing on developing and validating methods to detect micro- and macroplastics in soils and drainage waters, with an emphasis on how drainage water impacts municipal wastewater treatment, a key aspect of the study is analyzing plastic emissions from agricultural mulch films. We spoke to Carmen Wolf of the Institute for Environment and Energy, Technology and Analytics e.V. (IUTA) in Duisburg, Germany, corresponding author of a recent paper on the project, about the investigations involved and how separation science was used in their experimentation.

As the poultry sector in Côte d`Ivoire (The Ivory Coast) expands and huge quantities of waste are generated, researchers analyzed the risks associated with the discharge of poultry slaughterhouse waste in public landfill sites in Abidjan, the county’s largest city. Chemical and microbiological analysis of 30 poultry slaughter waste samples from 10 Abidjan communities was performed using high performance liquid chromatography (HPLC) and detection of pathogenic bacteria on specific media, respectively.

The nonsteroidal anti-inflammatory drug (NSAID) flunixin meglumine has been approved by the FDA for fever associated with bovine respiratory disease or mastitis and for control of pain from foot rot in cattle. A study determining the pharmacokinetics of a single dose of flunixin transdermal formulation in American bullfrogs used ultrahigh-pressure liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) to determine plasma flunixin concentrations.

Chromatography companies recognize significant opportunities in the biotech and pharma sectors, yet face uncertainty driven by rising tariffs and the growing integration of AI tools.

Researchers explored whether peels from different commercial and local apple samples could serve as a source of phenolic bioactive compounds potentially linked to the prevention of type 2 diabetes. The quantification of 37 individual phenolic compounds was performed by high performance liquid chromatography coupled with tandem mass spectrometry (HPLC–MS/MS).

Daisy Unsihuay Vila of Henry Ford Health (Detroit, Michigan) was awarded the 2025 Agilent Technologies and Females in Mass Spectrometry’s Darlene Solomon Award for her research focused on improving mass spectrometry (MS) techniques in clinical settings, particularly for drug monitoring and toxicology analysis.

A recent study evaluated the suitability of pyrolysis–gas chromatography-mass spectrometry (Py-GC–MS) for detecting and quantifying micro- and nanoplastics (MNPs) in human blood. LCGC International spoke to Cassandra Rauert of the Queensland Alliance for Environmental Health Sciences at The University of Queensland (Woolloongabba, Australia), corresponding author for the paper resulting from this study, about her team’s work.
