Micro-Snyder column or nitrogen blowdown? Explore the advantages, limitations, and EPA applications of two widely used concentration techniques for environmental and trace analysis.

Persistent organic pollutants (POPs) are a growing challenge for environmental laboratories. Discover how GC-HRAM MS and non-targeted screening help identify both regulated and previously unknown contaminants.

This study develops a GC-APCI-MS/MS method for detecting large PAHs in pyroplastics, identifying potential markers of burned plastic pollution.

Francais Femi Oloy discusses PCB monitoring in Nigerian rivers, including GC-ECD analysis, liquid–liquid extraction, sample cleanup, and challenges in trace pollutant detection.

How precise concentration of QuEChERS extracts helps laboratories meet EU Regulation 396/2005 requirements in pesticide residue analysis.

Comprehensive overview of microplastic pollution analysis, from extraction workflows and contamination control to nitrogen evaporation and advanced GC-MS, LC-MS/MS, and Py-GC-MS techniques.

This study presents a sensitive Py-GC–MS/MS method using dynamic reaction monitoring to quantify nano- and microplastics in water, sediment, and biota at nanogram levels.

Stringent Water Framework Directive requirements drive high analytical sensitivity. EQS limits, GC-MS determination of priority substances, and the critical role of sample preparation in practice.

A decade-long study from the Czech National Atmospheric Observatory shows that banned pesticides persist in the air decades later, driven by soil re-emission and slow environmental degradation.

Scalable Pyrolysis-GC/MS workflows reveal how microplastics move through the environment and the human body, from routine monitoring to high-resolution Orbitrap-based exposure science.
