Vacuum-assisted HS-SPME with GC×GC-MS significantly enhances honey analysis, enabling sensitive quantification of 5-HMF and detailed volatile profiling with improved signal intensity and greener operation.

Chemometric GC×GC–MS analysis revealed that Brazilian hop cultivars are chemically similar to imported hops of the same type, with differences in selected terpenes relevant to brewing quality.

GC–MS metabolomics revealed that soil-applied insecticides induce distinct metabolic changes in coffee seedlings, affecting sugar pathways and alkaloid biosynthesis beyond pest control.

A novel persistence-directed testing approach combined with nontarget GC-MS and LC-HRMS revealed a significant fraction of persistent chemicals in offshore oil platform produced waters.

Green UA-DLLME with GC–MS enables trace analysis of 12 carbonyl compounds in plant-based beverages, offering high sensitivity, accuracy, and sustainability.

Researchers at IOCB Prague developed a highly precise and ultra-stable fluorescent labeling method that stays attached even inside cells, enabling long-term, reliable tracking of biomolecules.

GC-MS and HS-SPME enabled quantitative and qualitative profiling of key rose alcohols in natural extracts, perfumes, and flowers, supporting adulteration detection and differentiation of fragrance compositions.

RECETOX researchers showed that some flame retardants in car interiors rise up to 700× in summer compared to winter, revealing strong temperature-driven exposure risks for drivers and passengers.

Pixel-based GC×GC-TOFMS preprocessing enables rapid chemometric comparison of Brazilian pre-salt oils, revealing subtle light-hydrocarbon patterns and distinguishing Barra Velha from Itapema.

Aroma analysis of six CBD hemp cultivars revealed 52 odor-active compounds, many new to hemp. Key terpenes and potent sulfur odorants drive distinct scent profiles across varieties.
