Diamond-Based SPE Phases

Scientists from Brigham Young University (Provo, Utah) and US Synthetic Corporation (Orem, Utah) developed C18, C8, and perfluorinated diamond-based reversed-phase solid-phase extraction (SPE) media. They examined alkyl chain functionalization, synthesis of the three phases, percent surface coverage, and column reusability, and the C18 phase was tested for stability, percent recovery, and column capacity. The results reportedly showed that the functionalized diamond phases do not have the same limitations as traditional silica-based SPE phases.
