Shim-pack GISS Series
Shim-pack GISS Series
High-speed analysis with ultra-high inertness and high durability
Shim-pack GISS series maintains the same ultra-high inertness and wider pH range as the Shim-pack GIST series while providing rapid separations with symmetric peaks. The optimization of surface area, pore size and chemical bonding delivers superior peak shapes, making these columns ideal for LC/MS/MS analysis.
Shim-pack GISS series also includes the 1.9μm and 3μm HP series for UHPLC analyses.
