PFAS are among the most persistent environmental contaminants. Explore LC-MS/MS, GC-MS, TOF, and HRMS approaches for PFAS detection, identification, and quantification.

Learn the most common causes of SPE cartridge flow problems and how to troubleshoot them. Identify issues related to samples, solvents, manifold pressure, and precipitation.

Low SPE recovery does not have to mean method failure. Learn how fraction collection and analysis can identify analyte losses and guide effective troubleshooting steps.

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

Proper drying of the SPE sorbent is a critical step to achieve high sensitivity, good reproducibility, and maximum analyte recovery, especially for complex sample matrices.

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.

How can you extend GC column lifetime and prevent contamination? Part 2 focuses on using liners with glass wool and proper column bake-out to maintain separation performance.

Dirty samples can quickly damage your GC column and shorten its lifetime. Learn simple, proven ways to protect your column, improve performance, and reduce downtime. Part 1 focuses on smart sample preparation.

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.

An SPE technical tip focused on identifying the sources of interferences and extra peaks observed after sample extraction.
