A high-performance liquid chromatography protocol for the analysis of brevetoxins has been developed using a silica hydride-based cholesterol column. Brevetoxins are neurotoxins produced by harmful algae that have additional potential as drugs for a

An amide phase based on a porous silica hydride support material is tested for retention characteristics in both the reversed-phase and aqueous normal-phase modes. A series of retention maps (capacity factor vs. mobile phase composition) were obtaine

The solid-phase extraction of several polyphenolic compounds with different silica hydride-based stationary phases, as well as an unmodified type-B silica, has been investigated. In particular, the propensities of these stationary phases to extract t

Pyridinoline and deoxypyridinoline crosslinks are biomarkers found in urine for collagen degradation in bone turnover. For the first time, a rapid, sensitive, and ion-pairing free method is described for the analysis of pyridinoline and deoxypyridino

A new LCMS approach is tested for the analysis of controlled substances using bath salts (cathinones) as a model system. Since the structure of cathinones have a polar functionality (the amine group) as well as an aromatic component, separation on th
