The extremely unique phase characteristics of Shim-pack GIST
Phenyl are critical to resolving compounds that could not be
separated with a C18 or C8 phase column.
In addition to p-p interactions, Shim-pack GIS Phenyl provides
hydrogen bonding secondary interactions, which results in
retaining polar compounds at the same time. As the phenyl
groups are directly bonded to the silica gel, Shim-pack GIS
Phenyl is also capable of the analysis of structural isomers due
to its high stereo-selectivity.
