General description

Ascentis Express HPLC columns, through the use of Fused-Core® particle technology, can provide you with both the high speed and high efficiencies of sub-2 μm particles while maintaining lower backpressures. The combination of high efficiency and low backpressure benefits UPLC® (or other ultra high pressure system) users, as well as conventional HPLC users.
Visit the Ascentis Express home page for more information on this new column technology.

Application


  • Recent trends in ultra-fast HPLC: new generation superficially porous silica columns.: This review explores the evolution and performance of superficially porous silica columns in high-performance liquid chromatography (HPLC), including those similar to the Ascentis Express C8, 2.7 μm. The focus is on the technology′s impact on enhancing analytical speed and efficiency (Ali et al., 2012).

  • Development and validation of an HPLC-MS/MS method to determine clopidogrel in human plasma. Use of incurred samples to test back-conversion.: This study details the development of an HPLC-MS/MS analytical method using columns such as the Ascentis Express C8, 2.7 μm, aimed at quantifying clopidogrel in plasma, demonstrating the column′s utility in clinical pharmacokinetic assessments (Silvestro et al., 2010).
