Six flue-cured tobacco varieties were analyzed by HS-GC-IMS and HS-SPME-GC-MS. Ninety-plus volatiles were identified, and 19 key compounds distinguished flavor differences.

Cows fed multispecies swards produced milk with more polyunsaturated and bioactive fatty acids than ryegrass systems, suggesting benefits for milk quality and consumer health.

A novel AF4-MALS and Py-GC-MS workflow enables size-resolved polymer analysis of nanoplastics in wastewater. It improves detection, quantification, and offers insights into polymer composition.

Brazilian stingless bee honey was analyzed via FT-MIR, NMR, and GC–MS. Chemometrics revealed species differences and correlations between phenolics and antioxidant capacity.

Fourier-transform NIR and volatilome-based HS-GC–IMS/MS methods fingerprint peach ripening stages, allowing PCA and PLS-DA models to differentiate ripeness and variety for optimal harvest.

A rapid FTIR method was developed to measure hydrogen isotope ratios in water. Using molecular bending vibrations, it achieved ~0.5% sensitivity and ~1% deviation, proving reliable for H2O/D2O mixtures.

Pyrolysis of HTPB/AP mixtures produces PAHs and aromatic C6 species absent in pure HTPB. Mass spectrometry confirms rapid PAH growth on μs time scales with pathways revealed by Pyr-GC-MS.

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.

Combining FT-MIR and GC-MS enables fast, multivariate analysis of agavins metabolism in Agave angustifolia and A. potatorum, linking MIR regions to GC-MS structural data for deeper insights.

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