    摘要： Embodiments of the present invention relate to solid phase extraction (“SPE”) apparatuses that include a sintered polycrystalline diamond (“PCD”) stationary phase and methods of performing SPE using a sintered PCD stationary phase. In one embodiment, an SPE cartridge includes a housing that comprises a proximal first end including a housing inlet, a distal second end including a housing outlet, and an interior space extending between the housing inlet and the housing outlet. An SPE stationary phase may be positioned within the interior space and includes an inlet and an outlet. The SPE stationary phase comprises a mass of sintered diamond grains including a plurality of passageways extending therethrough between the inlet and the outlet. In other embodiments, an SPE apparatus may employ a sintered PCD stationary phase in the form of a disk. In yet another embodiment of the present invention, an SPE stationary phase of an SPE apparatus may comprise un-sintered diamond particles.

    摘要： This invention is directed to treatments for dyed textile goods that will improve their fastness properties. More particularly, the invention is directed to certain fixatives that, when placed on the dyed textile, allow the dye to be permanently or substantially permanently affixed to the fabric. The dye-reactive fixative comprises a water-soluble or water-dispersible polymer or oligomer having reactive groups that react with a dye on a dyed web to affix the dye to the web.

    摘要： In one or more embodiments, a porous composite particulate material includes a plurality of composite particles including an acid-base-resistant core particle at least partially surrounded by one or more layers of acid-base-resistant shell particles. The shell particles are adhered to the core particle by a polymeric material. The shell particles and/or core particles may be made from an acid-base-resistant material that is stable in harsh chemical conditions. During application of the polymeric material/shell particle bilayer, the core particles are sonicated to homogenize the particle size distribution and minimize agglomeration of particles. Multiple bilayers of polymer/shell particles may be applied. In one embodiment, the core particle comprises generally spherical glassy carbon, while the shell particles may comprise nano-sized diamond particles. Other acid-base-resistant materials may be employed. The porous composite particulate materials may be used in separation technologies, including, but not limited to, chromatography and solid phase extraction.
