Researchers quantified urinary cotinine levels in children with asthma, analyzed correlation with asthma severity, and examined the relationship between parental smoking and urinary cotinine levels. Cotinine analysis was conducted using high-performance liquid chromatography (HPLC).

Seton Hall University has received a $10 million estate gift establishing the Thomas Tencza, PhD Endowed Professorship in Chemistry, providing long-term support for advanced research, graduate training, and separation science initiatives in its highly regarded chemistry and biochemistry programs.

A recent study demonstrated how analytical techniques can be used to differentiate between different types of whiskey.

Researchers at Japan’s National Research Institute of Brewing used ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS) to analyze the metabolome of sake and build predictive models of its sensory characteristics.

Petroleum contamination from leaking underground storage tanks, for example, is a significant concern for both the environment and human health. Thorough characterization of the contamination is required to form appropriate risk assessments and remediation strategies, but until now, the determination of total petroleum hydrocarbons (TPHs) in soil has typically involved a convoluted and labour-intensive process. In this article, the analysis of TPH in environmental media is simplified using flow-modulated GC×GC–FID with quantitation based on pre-defined compound groupings. This approach overcomes the drawbacks of conventional solvent fractionation approaches, by eliminating the need for sample fractionation and automating data processing workflows.

A joint study between York University and the University of Tehran evaluated conventional analytical methods, such as gas chromatography (GC), high-performance liquid chromatography (HPLC), and mass spectrometry (MS), as well as other emerging portable PAH detection technologies in hopes of significantly improving the health and safety of firefighters by reducing their long-term risks of cancer.

Researchers employed reflectance spectrometric analysis to quantify species-specific plumage coloration, and high performance liquid chromatography (HPLC) to elucidate the feather carotenoids of South Asian flameback woodpeckers to assess their pigment chemistries and genomic underpinnings.

This week, LCGC International published a variety of articles on hot topics in separation science. Some of the articles included in this week’s update explore topics such as the metabolic risk in horses, the bioactivities in chili pepper varieties, and a report on the analytical instrument market for Q2 2025. Below, we’ve highlighted some of the most popular articles that were published this week.

A recent study employed three brands of commercially available ready-to-heat roasted catfish to investigate the off-flavor substances present after reheating, utilizing gas chromatography-electronic nose (GC-E-Nose), GC-ion mobility spectrometry (GC-IMS), and GC-olfactory-mass spectrometry (GC-O-MS )in conjunction with sensory omics.

Analytical instrument makers reported strong Q2 2025 results, driven by sustained demand in the pharmaceutical and chemical industries, with consumables and recurring revenues outpacing instrument sales.

PerkinElmer expands globally with new facilities in the U.K. and China and launches a strategic partnership with Covaris and Hamilton to enhance laboratory solutions and diagnostics worldwide.

Twenty years ago, the fraud at Able Laboratories was uncovered. A chromatography data system (CDS) was at the center of the fraud. What have regulated laboratories learnt since then?

We highlight how chromatography is being used to analyze Irish whiskeys.

Researchers evaluated metabolic abnormalities in six neonatal Noma foals that died shortly after birth, using laboratory tests, pathological examinations, serum amino acid (AA) analyses, genetic analyses, and gas chromatography-mass spectrometry (GC-MS).

The concept of theoretical plates is the key measure of column efficiency in chromatography, linking Nobel Prize–winning theory with practical tools for achieving sharper peaks, better resolution, and reliable separations.
