Environmental Volatile Organic Compounds (VOCs) by Headspace Trap with GC–MS

LCGC International sat down with Jose Bernal to discuss his latest research in using pyrolysis gas chromatography–mass spectrometry (Py-GC–MS) and other chromatographic techniques in studying microplastics in food analysis.

A separation of ultra-short and long chain PFAS (C1-C18) is performed on a HALO®PCS Phenyl-Hexyl column along with a HALO®PFAS Delay column which demonstrates excellent retention for both hydrophilic and hydrophobic analytes.

Organic solvents are generally not compatible with ion chromatography (IC) systems. The approach presented here assists the use of organic solvents for sample preparation and provides a mechanism for the removal of the organic solvents from the chromatographic flow path.

The Chromatographic Society (ChromSoc) has announced the winners of the Martin Medal and the Silver Jubilee Medal for 2025. Professor Bogusław Buszewski of Nicolaus Copernicus University in Torun, Poland, has been awarded the prestigious Martin Medal, and the 2025 Silver Jubilee Medal has been awarded to Elia Psillakis of the Technical University of Crete in Greece.

Known as “forever chemicals”, PFAS exposure has been linked indirectly and directly to a range of potential health issues. The objective of this study was the development of an optimized sample preparation and LC–MS/MS method for the analysis of PFAS in serum for biomonitoring applications.

This paper demonstrates a sensitive and reliable method for speciating between toxic hexavalent chromium and non-toxic trivalent chromium in water using IC-ICP-MS.
