Advanced Sorbent Materials in Solid‐Phase Extraction: A Decade of Innovation and Future Perspectives

Chemistry–Methods, Volume 6, Issue 8, August 2026.
This review systematically summarizes five families of advanced sorbent materials for solid‐phase extraction (SPE): nanocarbons, porous frameworks (MOFs/COFs), smart polymers, biomass‐derived sorbents, and multifunctional composites. Key molecular interactions (π–π stacking, hydrogen bonding, electrostatic attraction, host–guest recognition) are ...

Green and Rapid Determination of Phthalates in Mineral Water From Virgin and Recycled PET Bottles

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT This study investigates the presence and quantification of phthalates released into mineral waters from virgin and recycled polyethylene terephthalate (PET) bottles. A green, solvent‐free analytical method based on solid‐phase microextraction (SPME) coupled with gas chromatography–mass spectrometry (GC/MS) was developed and validated to detect

Evaluating Stabilizers Effects on Aroma Release Dynamics in Ice Cream: A PTR‐ToF‐MS Analysis

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT Capturing the dynamic volatilome of frozen matrices during phase transitions remains an analytical challenge, typically requiring invasive sampling. This study employs proton transfer reaction time‐of‐flight mass spectrometry (PTR‐ToF‐MS) as a rapid, noninvasive technique that directly samples headspace volatiles without preconcentration to ...
