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.
