This study aimed to adapt and validate the QuEChERS method for extracting and purifying 19 persistent organic pollutants—11 organochlorine compounds and 8 polychlorinated biphenyls—for GC–MS (CNI mode) analysis in bird liver samples. After extraction with acetonitrile and salt phase separation, the extract was reconstituted in hexane and cleaned using sulfuric acid. Linearity was ≥0.9, and precis…

Nature Communications, Published online: 05 June 2026; doi:10.1038/s41467-026-74020-0 Monitoring structural changes in enzymes is essential for elucidating the mechanisms and dynamics of enzymatic catalysis, however, the transient conformational fluctuations involved in catalytic processes typically occur on microsecond-to-millisecond timescales, posing significant challenges for detection via co…

A new prototype takes mass spectrometry from analyzing a few molecules at a time to handling billions at once. Mass spectrometry is already a cornerstone technology for identifying what molecules are present in a sample and how much of each is there. However, most current instruments still examine molecules one at a time or in [...]

Pioneering scientists have created a miniature nuclear fireball and uncovered a surprise discovery in the realm of chemical reactions. Research conducted at Lawrence Livermore National Laboratory sought to fill potential gaps in knowledge of nuclear fallout models, with findings published in Analytical Chemistry. The study examined the behaviour of uranium, cerium, and caesium as these elements u…
