Henry, "Highly Selective Zirconia-based Phases for HPLC Applications," American Laboratory, 34(22), 18-25 (2002). The ZirChrom DiamondBond particle is carbon-clad zirconia, stable at all levels of pH. Now the entire operating range is available allowing chromotographers to achieve better separations. In addition, with DiamondBond-C18's unique bonding chemistry, the C18 ligands are attached to the surface with ultra-stable carbon-carbon bonds - so the columns are impervious to extremes of mobile phase chemistry and temperature. DiamondBondC18 opens up a whole new operating range to explore in chromatographic applications, helping you to find the best separation. ZirChrom DiamondBond-C18 is the first member of a family of new columns for chromatographic method development. These new tools give chromatographers unparalleled freedom and power to develop more robust separation methods. A completely new chromatographic material, DiamondBond-C18 eliminates the shortcomings of conventional ODS-silica columns by combining patented surface technology with ZirChrom's state-of-the-art particles.
