- High proportion of pore/surface area available to large molecules
Guard column requires Trident LC column protection system or Trident HPLC in-line guard cartridge holder.
Description
Viva columns are based on a wide-pore material designed for optimal large-molecule separations. Many commercial wide-pore silicas meet the standard 300 Å mean pore size but have broad distributions, leaving much of the surface area unavailable to larger molecules. Viva columns feature a narrow pore size distribution, allowing more silica surface to contribute to separation efficiency.
Since 2005, the Restek Biphenyl phase has provided greater dispersion than conventional phenyls and higher polarizability than phenyl hexyls. This results in increased retention for dipolar, unsaturated, or conjugated solutes, and enhanced orthogonal selectivity when using methanol mobile phases. Ideal for improving sensitivity and selectivity in LC-MS analyses.
