Porous Polymer Monoliths and Their Chromatographic Applications

Chromatography, despite being a technique over a century old, is a staple in modern chemical analysis. Its applications have become so broad since its inception due to developments in instrumentation, such as high-performance liquid chromatography and gas chromatography, and equally so due to the chemistries and structures of the stationary phases. Traditional chromatography columns are packed with fine particles of a porous mineral such as silica or alumina, but developments in silica and polymer chemistry have yielded the invention of monoliths: a continuous and highly porous block of material with high surface area for use as a column. Monoliths have unique properties and the use of organic polymer materials in place of silica has provided new capabilities and applications for chemical separations 1,2.
