CONDUCTIVE CONDUITS FOR CHEMICAL ANALYSES, AND METHODS FOR MAKING SUCH CONDUITS

摘要

A method for making a fluid-processing apparatus involves mixing a colloidal suspension with a matrix material, applying the mixture to a surface of a conduit, and curing the applied mixture to provide a conductive coating. A fluid-processing apparatus includes a conduit and a conductive layer adjacent to a surface of the conduit. The conductive layer includes graphite particles embedded in a matrix. The fluid-processing apparatus supports, for example, electrospray-ionization for mass spectrometry, capillary electrophoresis, or capillary electro- chromatography .
