Embodiments of the present invention are directed to porous resins for solid phase extractions. The resins feature at least one hydrophobic component, at least one hydrophilic component and at least one ion exchange functional group. The resins exhibit superior wetting and ion exchange performance.

Ion exchange porous resins for solid phase extraction and chromatography

A MALDI sample plateis disclosed which comprises a metallic substratehaving a circular groove or moat. A hydrophobic polytetrafluoroethylene layeris applied to the substrateand a central portionof the substrateis laser etched which roughens the surface of the substrate. A thin polystyrene layer is then applied to the polytetrafluoroethylene layerand the central portion

MALDI sample plate

Destructible surfactants and methods of using same are provided. The invention includes anionic surfactants having a dioxolane or dioxane functional group which enables the surfactant to be broken down under acidic conditions. The invention also includes methods of making anionic surfactants and methods of using anionic surfactants in a variety of applications.
