           Shim-pack GIST NH2


              Ideal for Sugar Analysis
              New high-purity porous spherical silica chemically bonded   Bonded Phase  Aminopropyl Group
             with the aminopropyl group ensures the superior stability of   Particle Size  3 μm, 5 μm
             Shim-pack GIST NH2. It is capable of the analysis of vitamin E   Pore Size  10 nm
             or simultaneous analysis of sugars that are hard to separate   Surface Area  350 m /g
                                                                                     2
             in reversed phase mode. In addition, due to being primarily   Carbon Loading  7 %
             amine-bound, Shim-pack GIST NH2 can analyze sugars with   End-capping  -
             no separation of anomers, even under low-temperature   pH Range     2 to 7.5
             conditions. Furthermore, Shim-pack GIST NH2 delivers highly   USP Code  L8
             reliable reproducibility and stability with accurate qualitative
             and quantitative results.
