  • Patent number: 11953434
    Abstract: Disclosed is a spectroscopic device, system, and method for measuring the concentration of one or more molecular species of interest in a gas, liquid or solid sample, where the device may be portable, may be commercially manufactured, and/or may be adapted to existing systems and/or integrated with new systems to provide optical gas sensing for such systems. The disclosed devices, systems, and methods can be particularly useful in monitoring the purity of, e.g., a certain gas species, including determining whether a gas mixture contains certain gas species above a set concentration limit.
    Type: Grant
    Filed: February 21, 2020
    Date of Patent: April 9, 2024
    Assignees: SHELL OIL COMPNY, THE TRUSTEES OF PRINCETON UNIVERSITY
    Inventors: Mark Zondlo, Lei Tao, Da Pan, Josh Collins, Paul Guiguizian, Howard Y. Bell, Alice Margaret Sophie Elliott, Patrick Minter Killough, Bernardus Maria Geertshuis, Herie Javier Soto

  • Publication number: 20220011316
    Abstract: A testing system and test cartridge for analyzing a sample of water from a water source for specific analyte levels. The test cartridge including a membrane filter that captures a target analyte while allowing a labelled conjugate to permeate through the membrane. The conjugate includes an analyte-specific labelled binding reagent to bind with the target analyte for optical detection. The direct membrane interrogation (i.e., on-filter detection), determines analyte levels without elution of the analyte from a filter thereby improving analyte recovering and assay sensitivity.

  • Publication number: 20050103869
    Abstract: The present invention relates to a method of detecting indicia on media and an imaging apparatus adapted to detect indicia on media. The indicia on the media contains near infrared absorbing dye and the method and apparatus comprises using dual detectors. One of the detectors is adapted to be used at the peak absorption wavelength of the dye in the indicia and the other detector is adapted to be used off of the peak to detect and remove variations caused by the media.
