Shim-pack GIS C18-P is designed with a polymerically bonded
octadecy group, which provides high steric selectivity for
separation of planar and non-planar compounds. It achieves
complete baseline separation of structurally similar compounds
such as vitamin D2 and D3 because of the planarity recognition
Shim-pack GIS C18-P is also ideal for the HPLC analysis of 16 PAH
compounds listed as target pollutants by the U.S. EPA.
