           Shim-pack GIST Phenyl


              Extremely Strong π-π Interactions
              The extremely unique phase characteristics of Shim-pack   Bonded Phase  Phenyl Group
             GIST Phenyl are critical to resolving compounds that could   Particle Size  2 μm, 3 μm, 5 μm
             not be separated with a C18 or C8 phase column.   Pore Size         10 nm
                                                               Surface Area      350 m /g
                                                                                     2
              In addition to π-π interactions, Shim-pack GIS Phenyl
                                                               Carbon Loading    10 %
             provides hydrogen bonding secondary interactions, which
             results in retaining polar compounds at the same time. As   End-capping  -
             the phenyl groups are directly bonded to the silica gel, Shim-  pH Range  2 to 7.5
             pack GIS Phenyl is also capable of the analysis of structural   USP Code  L11
             isomers due to its high stereo-selectivity.
