Pilot study shows human scent can survive firing on cartridge cases. Using olfactronics and olfactorics, traces were matched to volunteers to reveal who loaded the weapon.

Kupferschiefer black shale in SW Poland emits halomethanes, including tetrachloromethane, via Fe³⁺-catalyzed abiotic reactions, revealing a previously unknown natural source.

This study aims to validate a GC–MS method for detecting cannabinoids in seized gummies, enabling identification, quantification, and insights into their natural or synthetic origin and synthesis pathways.

This study evaluates PFAS emissions from firefighter jackets using TD-GC×GC-TOF MS, comparing layers and wear conditions to assess exposure routes and identify discriminating chemical features.

This study evaluates hydrogen, helium, and nitrogen as carrier gases in HPLC-GC-FID for MOH analysis in food, showing nitrogen as a suitable and effective alternative despite some peak broadening.

This study develops a GC×GC method using reconstructed TIC response factor surfaces to estimate compound concentrations without needing reference standards or molecular descriptors.

This study uses ESI FT–MS to analyze polar compounds in crude oils, assess their thermal stability, and propose an MS ratio that correlates with traditional GC–MS diagnostic indicators of thermal evolution.

In the article in the Environmental Sciences Europe journal, the researchers assessed the safety compliance of plastic toys in the European market, focusing on polybrominated diphenyl ethers (PBDEs).
