The European Commission's regulation on maximum levels for certain contaminants in food highlights the need for precise and reliable methods to quantify per- and polyfluoroalkyl substances (PFAS) in various food matrices. This article discusses development and validation of a robust method for analyzing 21 PFAS compounds in chicken eggs using solid-phase extraction (SPE) and liquid chromatography–mass spectrometry (LC–MS).
Vitamin D Determination Tested Using Liquid Chromatography–Tandem Mass Spectrometry
May 2nd 2024Scientists from Hangzhou Medical College recently recorded the effectiveness of novel quality control strategies for the determination of vitamin D using liquid chromatography–tandem mass spectrometry (LC–MS/MS).
High-Throughput 4D TIMS Method Accelerates Lipidomics Analysis
April 25th 2024Ultrahigh-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.
Traditional Chinese Medicine’s Effects on Liver Cancer Measured Using New UHPLC–QTOF-MS System
April 22nd 2024Scientists 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.

March 29th 2024The 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.
GC–TOF-MS Finds >250 Volatile Compounds in E-Cigarette Liquids
March 29th 2024A 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.
Inside the Laboratory: The Schug Group at the University of Texas at Arlington
March 22nd 2024In 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).
