GIST Series
Ultra-high inertness and high durability
Shim-pack GIST series columns are packed with newly developed high-purity porous spherical silica. Superior inertness not only improves analytical precision, but also increases column durability. Shim-pack GIST series is capable of tolerating a wider pH (1-10) situation, making it suitable for analysis of many different compounds.
C18, C8, Phenyl and NH2 columns are offered to cover an extended range of selectivity and meet diverse research and development needs.
Furthermore, Shim-pack GIST series is designed with various particle size ranges, which make it easy to transfer your analysis from ultra-high-speed to conventional methods.

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.
