This week we bring you application notes by KNAUER, Shimadzu, Thermo Fisher Scientific and Waters Corporation and technical note by Agilent Technologies!

Ultrashort-chain PFAS (USC-PFAS) are highly mobile, water-soluble and persistent contaminants. Learn about their sources, environmental fate, regulation and analytical challenges.

EU Drinking Water Directive 2020/2184 sets ultra-low limits for pesticides, PFAS, metals and endocrine disruptors. Learn how SPE and nitrogen evaporation enable LC-MS/MS compliance at ng/L levels.

Agricultural mulching films degrade into microplastics that affect soil properties, microbial life, and nitrogen cycling. A new European field study reveals real risks to soil health.

How the EU’s revised Urban Wastewater Treatment Directive is driving demand for ultra-sensitive LC-MS/MS workflows—and why nitrogen evaporation is critical for reliable micropollutant monitoring.

PFAS biomonitoring in fish and shellfish reveals how these “forever chemicals” accumulate in ecosystems. The article covers EU regulation, bioaccumulation pathways, and LC–MS/MS analysis.

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.

Organomation explains how PFAS-free nitrogen evaporators eliminate fluoropolymer contamination by replacing PTFE tape with a PTFE-free sealant, ensuring safe and reliable PFAS sample preparation.

Scientists from CATRIN and CEET developed a filtration membrane that removes bacteria and toxic heavy metals from water in one step, without energy or chemicals.
