Metal-free column - Excellent peak shape and sensitivity for metal coordinating compounds -

Column body
  • The Shim-pack Scepter uses an organic silica hybrid packing material with extremely low impurity metal.
  • The metal coordinative adsorption is suppressed by deactivating the column parts in contact with the solution.
