    Abstract: A multi-chambered pump-valve device for performing chemical processes, detections or analyses is described herein. The device includes a plurality of chambers having variable volumes in fluid communication with one another via one or more passageways. Liquid may be directed through the device by merely changing the volumes of two or more chambers. Despite the simplicity of the mode for transferring liquids in the device, complex chemical processing sequences may be performed using the device. A plurality of devices may be incorporated into a larger apparatus so that a plurality of chemical processing operations may be performed substantially simultaneously in parallel.

    Abstract: A composition is disclosed comprising a hydrophobic monomer having the structure: CH2═CR4C(O)NHC(R1R1)(C(R1R1))nC(O)XR3 wherein n is an integer of 0 or 1; R1 is independently selected from at least one of: a hydrogen atom, alkyls aryls, and alkylaryls, wherein the alkyls, aryls, and alkylaryls have a total of 10 carbon atoms or less; R3 is a hydrophobic group selected from at least one of: alkyls, aryls, alkylaryls and ethers, wherein the alkyls, aryls, alkylaryls and ethers have a total number of carbon atoms ranging from 4 to 30; R4 H or CH3; X is O or NH. In some embodiments the hydrophobic monomer is derived from an amine or an alcohol (HXR3) that has a hydrophilicity index of 25 or less. A polymerizable composition comprising the hydrophobic monomer is disclosed, which optionally may comprise a cross-linking monomer and/or a non-cross-linking monomer. This polymerizable mixture may be used to from hydrophobically-derivatized supports, which may be used in applications such as hydrophobic interaction chromatography.
