    摘要： Described is a device for collecting a fluid sample, such as a biological fluid sample. The device includes a planar collection substrate having an absorbent material. The planar collection substrate includes an impermeable region and a sample collection region. The impermeable region is impermeable to the fluid sample and is embedded in the planar collection substrate in a spatial pattern. The sample collection region is in an area excluded from the spatial pattern and has a shape and a size defined by the spatial pattern. The sample collection region is configured to receive a known volume of the fluid sample. In an alternative form, the device includes a sample collection element disposed in an impermeable planar holder and, in another alternative form, the device includes an absorbent material disposed inside an impermeable tube wall.

    摘要： A method for performing hydrophobic interaction chromatography includes providing at least one wall defining a chamber having an inlet and an exit, and a stationary phase disposed within the chamber. The stationary phase comprises particles or monolith having a hydrophobic surface and a hydrophilic ligand. The method also includes loading a sample onto the stationary phase in the chamber and flowing the sample over the stationary phase. The sample is separated into one or more compositions by hydrophobic interaction between the stationary phase and the one or more compositions.

    摘要： A method for removing an organic solute from a solution, comprising contacting the solution with a polymer formed by copolymerizing one or more hydrophobic monomers and one or more hydrophilic monomers, whereby the solute is adsorbed onto the polymer. The solution can comprise a polar solvent such as a polar organic solvent or water or an aqueous buffer. The hydrophobic monomer can be, for example, divinylbenzene. The hydrophilic monomer can be, for example, a heterocyclic monomer, such as a vinylpyridine or N-vinylpyrrolidone.
