  • Publication number: 20250283802
    Abstract: Disclosed are a system, kit, and method for assessing the corrosion tendencies of metal alloys in aqueous solutions. In one embodiment, a metal alloy sample, is exposed to a water sample, and the aqueous solution, is tested for indicative metal ions using reagents, that undergo spectral changes. The test compares the metal alloy sample exposed aqueous solution, to an unexposed spectral reference standard, to determine corrosion extent, anticorrosive treatment effectiveness, and optimal treatment concentrations. The kit may include colorogenic and/or fluorogenic reagents, spectral reference standards, and the system may incorporate a dual-detection spectrometry instrument for precise recorded analysis.

  • Patent number: 11914084
    Abstract: For determining whether oil waste at a field testing site is exempt from selected naturally occurring radioactive material (NORM) waste regulations, a measurement apparatus including a detection module that determine radioactivity counts per minute for an oil waste sample is utilized. The measurement apparatus includes an analysis module that uses a first nonlinear transfer function to determine a mass for the oil waste based on a volume of solids determined via BS&W testing. The analysis module uses a second nonlinear transfer function to determine a maximum radioactivity level for the sample which is then normalized to picoCuries/g. The normalized maximum radioactivity level per gram is compared to a NORM exemption level for a selected region and communicated to entities at the field-testing site and optionally to other entities. A system and a method perform the functions of the measurement apparatus.

  • Publication number: 20080032327
    Abstract: Method and apparatus for the detection of microbes in liquids, in air and on non-living surfaces in which samples are exposed to frequency-modulated electromagnetic radiation of specific energies capable of exciting various metabolites, cofactors and cellular and spore components, with the microbial cells to be sampled (and more specifically the excited metabolites, cofactors and/or other cellular components) contained therein emit fluorescence that can be measured that is similarly frequency-modulated provided that the excitation frequencies are longer than the fluorescence lifetime of the excited intrinsic microbial fluorophore.

  • Publication number: 20060257929
    Abstract: The present invention describes a method for the rapid binding of pathogenic microorganisms and their toxic proteins with ligands that have been covalently tethered at some distance from the surface of a substrate. Ligands directed to microbes are covalently attached to the substrate surface by tethers that are between 35 ? and 50 ? in length for optimal binding efficacy. Ligands directed to capture and concentrate proteinaceous materials are covalently attached to the substrate surface by tethers that are between 35 ? and 50 ? in length for optimum assay kinetics. The ligands described herein include heme compounds, siderophores, polysaccharides, and peptides specific for toxic proteins, outer membrane proteins and conjugated lipids. Non-binding components of the solution to be analyzed are separated from the bound fraction and binding is confirmed by detection of the analyte via microscopy, fluorescence, epifluorescence, luminescence, phosphorescence, radioactivity, or optical absorbance.

  • Publication number: 20050032115
    Abstract: The present invention describes a method for the binding of pathogenic microorganisms and their toxic proteins with ligands that have been covalently tethered at some distance from the surface of a substrate: distances of at least fifteen ? are required for microorganism binding ligand tethers and at least six ? are required for protein binding ligand tethers. The ligands described herein include heme compounds, siderophores, polysaccharides, and peptides specific for toxic proteins, outer membrane proteins and conjugated lipids. Non-binding components of the solution to be analyzed are separated from the bound fraction and binding is confirmed by detection of the analyte via microscopy, fluorescence, epifluorescence, luminescence, phosphorescence, radioactivity, or optical absorbance. By patterning numerous ligands in an array on a substrate surface it is possible to taxonomically identify the microorganism by analysis of the binding pattern of the sample to the array.
