Messina Institute of Technology scientists used gas chromatography–mass spectrometry (GC–MS) to profile illegal samples of Cannabis sativa L.

Separation and Characterization of Macromolecules 11 (SCM-11) will take place from 22–24 January 2025 in Amsterdam, The Netherlands.

The 54th International Symposium on High Performance Liquid Phase Separations and Related Techniques (HPLC 2025) will be held from Sunday through Thursday, 15–19 June 2025, in Bruges, Belgium. LCGC International spoke to the Scientific Committee to find out what’s in store.

LCGC International spoke with Jim Gearing, Associate Vice President of Marketing, Agilent Gas Phase Separations Division; Massimo Santoro, Group Business Development Director at Markes International; Ed Connor, GC Product Manager at Peak Scientific; and Bruce Richter, Vice President of Research & Development at Restek Corporation.

LCGC International spoke to Phil Marriott and Humberto Bizzo about a recent paper they published identifying the incorrect use of retention indices in gas chromatography and how this problem can be rectified in practice.

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.

In the testing of six different oat brands, headspace sorptive extraction and comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC–TOF-MS) reveal how various packaging types can affect and alter the oats’ volatile profile, underscoring the potential impact of packaging on food quality.

Using a solid phase microextraction gas chromatography-mass spectrometry (SPME GC-MS)-based metabolomics approach, a recent study by the School of Life Sciences and Technology at Institut Teknologi Bandung (Indonesia) investigated the impact of environmental factors (including temperature, rainfall, and altitude) on volatile metabolite profiles of Robusta green coffee beans from West Java.

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 installment of Tips & Tricks focuses on the determination of the molar mass using a light scattering detector as an absolute detection method.
