Performance evaluation of a scent transfer unit for sampling of explosives and their residues to investigate nuisance alerts

Journal of Forensic Sciences, EarlyView.
Abstract Volatile organic compounds associated with explosives such as Composition C‐4 serve as important targets for canine training as well as field analysis. In parallel, 1‐bromooctane (1‐BO) is a benchmark to contextualize canine performance and aid interpretation of results.

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds

Optimized SPE‐HPLC‐FLD Method for the Simultaneous Determination of Olaparib, Propranolol, and Furosemide in Human Urine

Biomedical Chromatography, Volume 40, Issue 8, August 2026.
ABSTRACT Olaparib belongs to the PARP inhibitors and is widely used as an anticancer drug. Due to frequent side effects, it is usually co‐administered with an antihypertensive, such as propranolol and/or an antidiuretic, such as furosemide. In this study, a highly sensitive HPLC‐FLD method was developed for the simultaneous determination of the three ...
