Pinnacle DB columns are 100% manufactured by Restek in our Bellefonte, Pennsylvania facility. Because performance begins with the support, our Pinnacle DB UHPLC columns start with base-deactivated spherical silica that is optimized for UHPLC stability. From there, we bond them with a wide variety of phases to give chromatographers a stable and selective column. Get the most out of your UHPLC system. Combine selectivity and efficiency by using Restek Pinnacle DB UHPLC columns.
Our C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. Like our C18, this general-purpose Restek C8 is suitable for a wide range of compounds from acidic through slightly basic.
