Monoliths are chromatography sorbents cast as a homogenous phase into chromatography columns as a single, continuous piece. In contrast, regular chromatographic solvents are packed as individual particles. In this month's "Column Watch," the guest columnists compare three of these novel sorbents with a conventional packed-particle column in terms of porosity, static, and dynamic capacity. Monoliths show flow rate–independent separation efficiency and dynamic capacity as well as higher porosity than conventional columns.

January 14th 2025University of Valencia scientists recently developed a method using solid-phase extraction (SPE) followed by high-performance liquid chromatography coupled to high-resolution mass spectrometry (HPLC–HRMS/MS) for detecting microplastics and other harmful substances in textiles.
