Shim-pack 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, C18 AQ, C8, Phenyl, Phenyl-Hexyl 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.

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.
