    摘要： Method comprising providing at least one solid carbide chemical compound and reducing a metal cation with use of the solid carbide chemical compound. A method comprising producing elemental carbon material from the oxidation of carbide in at least one carbide chemical compound (e.g., calcium carbide) in at least one anode of an electrochemical cell apparatus, such as a galvanic cell apparatus. The cathode can be a variety of metals such as zinc or tin. The reaction can be carried out at room temperature and normal pressure. An external voltage also can be applied, and different forms of carbon can be produced depending on the reactants used and voltage applied. For carrying out the method, an apparatus comprising at least one galvanic cell comprising: at least one anode comprising at least one carbide chemical compound, and at least one cathode. For carrying out the method and constructing the apparatus, an electrode structure comprising at least one carbide chemical compound, wherein the carbide chemical compound is a salt-like carbide; and at least one electronically conductive element different from the carbide. Carbon compositions of various forms are also prepared by the methods and apparatus and with use of the electrode structure. Large pieces of pure carbon can be produced. Post-reaction processing of the carbon can be carried out such as exfoliation.

    摘要： The present invention provides an apparatus and a method wherein the movement of analytes on a chromatographic separation column is controlled by the manipulation of isocratic and gradient flow. Such manipulation allows for a distinct set of analytes to be eluted from the chromatography column and delivered downstream for further separation and/or processing while the remainder of the sample remains in a “holding pattern” on the chromatography column. As such, the present invention allows for a small portion of the sample to be processed downstream of the column while substantially eliminating undesirable isocratic elution from the column during such downstream processing. Once the downstream processing has been completed, the column of the present invention elutes a second distinct analyte and the remainder of the sample is maintained in a holding pattern. The process may be repeated until the entire sample has been eluted from the chromatography column.

    摘要： The present invention provides an apparatus and method of utilizing bi-directional capillary electrophoresis (nullCEnull) device. In one embodiment, cations are drawn into a first uncharged channel towards a negative electrode and anions are drawn into a second uncharged channel towards a positive electrode. The uncharged channels allows for minimal interaction between the sample and the walls of the channel which allows for minimal sample loss. The present invention also provides a method of separating anions from cations. The method comprises delivering the mixture to a bi-directional CE device. Following delivery, cations are drawn into a first uncharged channel towards a negative electrode and anions are drawn into a second uncharged channel towards a positive electrode. In one aspect of the present invention, the bi-directional CE device engages a microfluidic proteome analysis system.
