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.

A PLE–Py-GC/MS method was optimized for PE, PET, PP, and PS in wastewater. Results show MP detection is strongly influenced by extraction, pyrolysis, and calibration parameters.

A green HS-HiSorb-TD-GC-MS method for 12 DBPs in drinking water shows high sensitivity, accuracy, and compliance with EU 2020/2184, supporting sustainable water quality monitoring.
