PS-DVB Monolithic Columns Applied in A Microcolumn Switching Set-up for the Analysis of Peptides and Proteins

Polystyrene-divinylbenzene (PS-DVB) trap columns have been evaluated for microcolumn switching applications. In contrast to traditional stationary phases, which consist of packed particles, the monolithic separation medium is made of a continuous, rigid polymeric rod with a porous structure. The absence of intraparticular void volume increases separation efficiency, allowing for faster separations. Column lifetime is higher compared to packed columns.
