Chromegabond C22 is a highly retentive stationary phase in which hydrocarbon C22 groups are bonded to an ultra-high purity support. The C22 is monomerical bound and is nonendcapped allowing this stationary to be used under wide variety of mobile phase compositions. This phase exhibits even greater hydrophobic interaction than the Chromegabond HC column. The Chromegabond C22 is ideally suited for the separation of triglycerides, PAHs, and steroids.
Chromegabond Cyano HS
Chromegabond Cyano HS Columns based on cyanopropyl bonding to high surface area silica to provide superior, reproducible separations and long column life with excellent peak symmetry. Can be used to separate polar compounds in both reverse phase and normal phase chromatography.
Chromegabond Phenyl BD
Chromegabond Phenyl BD is a highly base deactivated materail using steric shielding which can be used for moderately polar compounds. Retention characteristics are similar to C8 packing, but with different selectivity for polycyclic aromatic hydrocarbons, polar aromatics and fatty acids.
Chromegabond PSC C8/C18
Chromegabond PSC (pharmaceutical separation column) is prepared by using a mixture of C8 and C18 groups. In addition to this unique bonding arrangement, PSC columns incorporate technology that we have developed which enables us to tightly control the level of residual silanol groups. We utilize this technology to produce PSC columns with a tightly controlled number of residual silanol groups. These columns are able to retain both highly polar and hydrophobic compounds.
