Liquid Chromatography (LC/HPLC)

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.

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.

The serum/plasma estradiol is useful for diagnosis, pathology, and therapeutic efficacy monitoring of estrogen-dependent diseases, according to the authors.

Scientists from Anhui University of Chinese Medicine in Hefei, China recently investigated the mechanisms behind what makes huachansu tablets, a type of traditional Chinese medicine (TCM), effective against liver cancer.

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 from Auburn University recently investigated how natural deep eutectic solvents (NADES) can be incorporated into high-performance liquid chromatography (HPLC) mobile phases.

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).
