    摘要: A system and method for capillary electrophoresis are provided for analyzing a macromolecule prepared from a complex liquid mixture. In particular applications, methods and apparatus are provided for separating and analyzing a solution containing a denatured macromolecule by employing a stationary capillary electrophoresis apparatus. An apparatus for capillary electrophoresis includes an inlet chamber and a capillary electrophoresis column. One end of the column is fixed at the interior of the inlet chamber. The column has a length of at least about 20 centimeters. Also included is a liquid source adapted for automatic control. The liquid source supplies a liquid sample through an input valve into the inlet chamber so that the sample is in fluid communication with the end of the column. A method for capillary electrophoresis includes automatically supplying the liquid sample to the apparatus.

    摘要: A high-voltage capacitive electrostatic device is used to improve the performance of membrane-separation processes, particularly reverse-osmosis units, wherein species of a given ionic polarity are separated from water. The device is immersed in the water flowing across the membranes and is operated continuously at very high voltages, preferably greater than 30,000 volts DC. The charge on the wetted surface of the suspended particles is altered by the electrostatic field so generated and is found to reduce biofilm formation, thereby materially enhancing the performance of the membrane-separation system. The application of high-voltage electrostatic fields is also found to reduce corrosion of metallic surfaces in the system.

    摘要: A portable oxidant generator for generating a chlorine or chlor-oxygen solution suitable for sterilizing contaminated drinking water, thereby providing a water disinfection system and potable water. The oxidant generator includes an electrolytic chamber and a power supply or source. The chamber holds a salt brine solution such that the solution is in contact with an anode and cathode included in the chamber. The power supply provides electrical charge that is passed between the anode and cathode through the salt brine solution. In the preferred embodiment of the present invention, a combination manual pump/switch is activated and injects electrolyte into the cell chamber and electrolyzes the solution. In one embodiment, as electrolysis proceeds, hydrogen gas is liberated and causes a gas pressure within the cell chamber thereby forcing the freshly generated oxidant solution from the cell. In another embodiment, as electrolysis proceeds, hydrogen gas is liberated and causes gas pressure within the sealed cell chamber which acts against a spring loaded piston thereby increasing the chamber volume to minimize pressure buildup, and to maintain the electrolyte in contact with the anode and cathode throughout the electrolysis process irrespective of the orientation of the device. When electrolysis is complete, an electric valve is actuated that allows the freshly produced oxidant to be discharged in to the drinking container to provide disinfection and render the water potable.

    摘要: The invention defines a device for the separation of fluid mixtures, comprising one or several membranes, in which the fluid mixture passes along one side of the membranes while, on the other side, a partial pressure of the constituent to be separated is maintained which is lower than the pressure in the fluid mixture.The inventive device is characterized by the fact that at least one heatable membrane is provided. The selective (separating) portion of the membrane may be a porous or a pervaporation membrane.The membrane may also comprise a supporting structure in addition to the selective portion, which may be made of a porous material in a preferred embodiment.Another preferred embodiment comprises a membrane coated with a material which is preferably wetted by the constituent to be separated by the respective membrane.

    摘要: A combination electrodialysis method and apparatus comprising ultrafiltration membrane cell pairs interposed between ionselective membranes. The solution to be treated is fed to one side of the ultrafiltration membrane cell and an electric field is applied across the assembly. Ions of one polarity pass through one ion-selective membrane while ions of the opposite polarity pass through the ultrafiltration membrane and the other ionselective membrane while the ultrafiltration membrane rejects the larger sized particles and/or molecules.

    摘要: Various embodiments are described herein a membrane that may be used to affect the translocation of polymers through at least one nanopore in the membrane by incorporating an enlarged cavity within the nanopore where the cavity size is selected along with an external force strength so that a translocation time of polymers through the nanopore is affected and may result in a non-monotonic function of polymer chain length, provide a low-pass application or a bioreactor application, for example. Various combinations of such membranes may be used in polymer filtration devices.
