Shim-pack GIST Series

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, 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.
