    摘要: A readily disposable ion selective electrode assembly, free of onboard reagents, for use in analyzers has a reference element and plural sensor elements linearly positioned in parallel on a substrate. An elastomeric flow channel member containing two parallel grooves creates flow channels on the substrate above the elements. The substrate holds the elastomer in compression and is retained by snaps injection molded into a housing. Electrical contacts and leakfree fluidic connections are provided by spring loaded connectors through the housing. Reference and sample fluids are drawn through the respective flow channels and come together to form a liquid junction downstream from the sensor elements. Bubbles, that might otherwise cause erroneous results, are detected.

    摘要: This invention relates to a method for enhanced recovery of petroleum from a subterranean oil-bearing formation. More particularly, this invention relates to secondary or tertiary recovery of oil employing a polymer thickened aqueous drive fluid. The polymeric viscosifier for the drive fluid is selected from a class of hydrophobically associating water soluble polymers containing one or more water soluble monomers and a water insoluble monomer or group. The water soluble groups are acrylamide and a salt of an ethylenically unsaturated sulfonic acid and the water insoluble group is a higher alkyl acrylamide. These polymers, when dissolved in an aqueous brine solution, have the ability to substantially increase the viscosity of the solution. The control of displacement fluid mobility results in more uniform sweep efficiency and improved oil recovery. In addition, aqueous solutions of these hydrophobically associating polymers exhibit enhanced viscosification, reduced salt sensitivity and other desirable rheological properties found useful in chemically enhanced oil recovery processes.

    摘要: A disposable integrated miniaturized array of chemical sensors for analyzing concurrently a number of analytes in a fluid sample is described. Each sensor is a complete electrochemical cell consisting of its own individual reference and indicator electrodes and is selective with respect to a particular analyte in the sample.Where required, a sensor can be individually calibrated, such that each analysis can be read directly.

    摘要: A method, for microcoulometric determination either of the activity of an enzyme in a liquid sample or the concentration of a substrate for a reaction involving a change in a coenzyme from a first form thereof to a second form. At intervals during the reaction, both coenzyme forms are measured essentially simultaneously utilizing an electrolytic cell, to indicate either such enzyme activity or substrate concentration, depending upon which is the unknown factor.
