Abstract: Embodiments of the present invention are directed to an apparatus and method for performing parallel processes. One embodiment of the present invention is directed to an apparatus for performing a process having a plurality of steps in which each step is performed in a vessel by flowing a fluid through said vessel. The steps of the process comprise at least a first step and at least one subsequent step. At least one of the subsequent steps is a final step, and each step has a time associated with its performance, a step period. At least one step has a longest step period, and the total number of steps, times the longest step period equals a process period. The apparatus comprises a plurality of vessels. Each of the plurality of vessels is for performing sequentially all the steps of the process in the process period and each of the plurality of vessels is for performing each step of the process in the longest step period.

Abstract: Destructible surfactants and methods of using same are provided. The invention includes anionic surfactants having a dioxolane or dioxane functional group that enable degradation of the surfactant under acidic conditions. The invention also includes methods of using anionic surfactants in a variety of applications relating to samples containing small molecules.

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