LC–MS

Scientists from the University of Córdoba in Córdoba, Spain recently used liquid chromatography–tandem mass spectrometry (LC–MS/MS) to comprehensively profile human ceramides to determine their reactions to diseases.

A recent study used ultrahigh-pressure liquid chromatography (UHPLC) to identify traces of drugs on smartphones.

Ultrahigh-pressure liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) had been previously proposed for untargeted lipidomics analysis, but this updated approach was reported by the authors to reduce run time to 4 min.

Scientists from the Netherlands created a new LC–MS/MS assay to test new small molecular inhibitors (SMIs) and their effectiveness in prognosing lung cancer.

Chromatographic and spectroscopic techniques alike were reviewed for their current effectiveness and future potential in this lecture session at Analytica 2024.

The discovery of a novel lipid not yet seen in plants was found in four herbal teas using multivariate principal component analysis.

In this interview, Kevin Schug discusses his work using untargeted analysis and differentiation of psilocybin mushroom strains.

This month we interview David Steiner, head of product development at LVA GmbH–Lebensmittelversuchsanstalt in Klosterneuburg, Austria about his work developing liquid chromatography–tandem mass spectrometry (LC–MS/MS) multiclass methods for classification of feedstuff, including replication of model complex feedstuffs in the analytical laboratory.

The 26th Norwegian Symposium on Chromatography was held 21–23 January 2024. The symposium has strong traditions in the Norwegian separation science community, serving as a forum for excellent scientific talks, networking, and social events.

A study has used gas chromatography coupled to a time-of-flight mass spectrometer to build an electron ionization mass spectra database of more than 250 chemicals classified as either volatile or semi-volatile compounds. An additional, confirmatory layer of liquid chromatography–mass spectrometry analysis was subsequently performed.

Scientists recently tested a new system for detecting and extracting favipiravir from plasma samples.

Scientists from the Affiliated Hospital of Putian University recently analyzed the dysregulation of lipid metabolism in patients suffering from chronic hepatitis B patients.

This week, LCGC International published a variety of articles on the hottest topics in chromatography and beyond. Below, we’ve highlighted some of the most popular articles, according to our readers. Happy reading!

In this edition of “Inside the Laboratory,” Kevin Schug, PhD, a full professor of chemistry at the University of Texas at Arlington, discusses his laboratory’s group work in environmental monitoring around water and soil quality near oil and gas extraction, using techniques such as liquid chromatography (LC), gas chromatography (GC), supercritical fluid chromatography (SFC), and coupling these techniques with mass spectrometry (MS).

In a recent study from the GITAM School of Pharmacy, two scientists used different liquid chromatography techniques to assess the properties of ozenoxacin (OXC) and its degradation products.

In a recent review article, researchers from Concordia University examined recent advancements in LC–MS workflows for tissue lipidomics.
