United Science recently developed a series of novel carbon modified porous silica materials for use in analytical and
preparative separations, and as solid-phase extraction media. The analytical materials exhibit unique characteristics scompared to other commercially available carbon phases as they are substantially more stable at high pressures andexhibit acceptable mass transfer characteristics. Users of carbon-based phases are aware that some compounds are very difficult to elute from existing commercial carbon-based materials. These new materials  address this problem through both the ability to adjust the carbon loading on the underlying substrate, and by using a relatively inert substrate.
