The Determination of Trace Per- and Polyfluoroalkyl Substances and Their Precursors Migrated into Food Simulants from Food Contact Materials by Liquid Chromatography–MS/MS and Gas Chromatography–MS/MS
An increasing range of per- and polyfluoroalkyl substances (PFAS) has been found migrating from food contact material into food. This article establishes an integrated analytical approach combining HPLC–MS/MS and GC–MS/MS to detect 36 such PFAS.

This integrated analytical approach combines HPLC–MS/MS and GC–MS/MS to detect 36 PFAS migrating into food simulants from packaging.
When Do We Need Sub2m Superficially Porous Particles for Liquid Chromatography Separations
The use of superficially porous particles (SPPs) for modern high performance liquid chromatography (HPLC) is now very common. Initially, SPPs rose as an alternative to sub-2-µm fully porous particles (FPPs). In recent years, many column manufacturers have developed 2-µm and smaller SPP-based products. This article investigates the practical utility of these smaller SPP designs.

When Do We Need Sub-2-μm Superficially Porous Particles for Liquid Chromatography Separations?
Many manufacturers now offer columns using superficially porous particles that are 2-µm and smaller. When should you use them?
