Chromegabond LS

Chromegabond LS (Lipophilic Separations) has been developed for analysis of lipophilic analytes such as fat-soluble vitamins, fatty acids, aliphatic pharmaceutical, and surfactants. The development of this new stationary phase evolved from our experience with fluorine based stationary phases. Many lipophilic compounds such as fat-soluble vitamins can be analyzed using reversed phase conditions on fluoro-phases.

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.

Chromegabond WR C18

Chromegabond WR (Wide Range) is specially deactivated to produce superior peak shapes for amines and acids. Chromegabond WR C18 superior performance is the result of a multistep process beginning with ultra-pure synthetically produced spherical silica. The ultra-pure silica particles are then fully hydroxylated before they undergo an extensive bonding monomeric C18 alkyl chains, using proprietary bonding procedures. The bonded particles are then exhaustively endcapped to react any remaining silanol groups yielding columns that are much more resistant to degradation by acidic and basic mobile phase compositions, while improving peak shapes for amines and acids.
