Velaris has acquired Markes International from Schauenburg International, strengthening its automated sample preparation portfolio, expanding its global presence, and enhancing support for laboratories across multiple end markets.

A recent study investigated the nutritional composition, bioactive compounds, and in vitro rumen fermentation characteristics of two tropical seaweeds, brown seaweed (Sargassum binderi) and green seaweed (Kappaphycus striatum), as potential functional feed additives for ruminant livestock profiled amino acids and fatty acids using HPLC and GC-FID, respectively.

Gas analyzers are evolving to meet modern demands, enhancing legacy systems with real-time insights and connectivity for improved operational efficiency and compliance.

To characterize the per- and polyfluoroalkyl substance (PFAS) content and migration potential of winter gloves and conduct a screening-level risk assessment of perfluorooctanoic acid (PFOA) and perfluorohexanoic acid (PFHxA) glove exposures in children aged 2-6 (considering both hand-to-mouth transfer and dermal absorption), experimental data were generated through total fluorine analysis, liquid chromatography–tandem mass spectrometry (LC–MS/MS), gas chromatography–tandem mass spectrometry (GC–MS/MS), and leachate testing of individual glove components across eight glove brands.

A review of some of the content highlights from LCGC International in 2025.

Research conducted by the Department of Food Science and Technology of Oregon State University and the Legacy Research Institute of Dow Neurobiology addressed this gap by developing a standardized aroma lexicon and associated sensory methodology, supported by GC-MS analysis of terpenes and terpenoids plus GC-PFPD analysis of volatile sulfur compounds. LCGC International spoke to Thomas H. Shellhammer of Oregon State University about this work.

In its 2025 industry survey, LCGC International looked beyond the numbers to uncover the challenges, priorities, and outlook shaping the chromatography community, and what lies ahead in 2026.

As a long-standing member of the chromatography community, I am continually awestruck by the rate of change we consistently experience. Through the collective efforts of an entire community, we realize a fast-paced evolution that serves the world. In this article, we will aim to make the rapidly expanding and dynamic field of biopharmaceuticals approachable by taking a high-level look into its most recent success: peptide-based therapeutics.

Aiming to determine the presence of heroin, fentanyl, amphetamine-type stimulants (ATS), xylazine, and other substances in Tijuana and Mexicali, Baja California, researchers randomly selected 300 drug residues from confiscated syringe plungers. After analyzing them with gas chromatography–mass spectrometry (GC–MS) and BTNX test strips for ATS and fentanyl and its analogs, the test strips showed a high positive predictive value of 81% when compared with GC–MS.

In this second installment of a multi-part series, we describe the principles of ion-pair reversed-phase high performance liquid chromatography, discuss strategies for method development, and provide practical tips for robust liquid chromatography analyses of oligonucleotide mixtures.

Research conducted at the Federal University of Pelotas (Brazil) investigated the formulation of oleogels based on Butia seed oil and their potential as a replacement for hydrogenated fats in cookies. Gas chromatography (GC) was used to determine the fatty acid profile and identify and quantify volatile organic compounds (VOCs).

Join us as we explore the innovations that defined 2025—and what they mean for the future of the field.

UHPLC-QTOF metabolomics and the Global Natural Products Social Molecular Networking (GNPS) platform revealed 185 secondary metabolites in Egyptian blue lily, which link flavonoid-rich flowers to antioxidant neuroprotective potential activities.
