  • Patent number: 11079324
    Abstract: A method for implementation by a laser spectrometer is provided. The method includes first scanning, by a control unit using a first set of laser spectrometer operating parameters, a first wavelength range by adjusting a wavelength of light of a beam emitted by a laser light source and passing through a sample gas. The first wavelength range encompasses a first spectral feature corresponding to a first constituent. The method also includes at least one second scanning, by the control unit using a second set of laser spectrometer operating parameters, a second wavelength range by adjusting the wavelength of light emitted from the laser light source and passing through the sample gas. The second wavelength range has a second spectral feature corresponding to at least one second constituent. The control unit also determines a first concentration of the first constituent and a second concentration of the at least one second constituent.

  • Publication number: 20120152764
    Abstract: A hemoglobin-detecting electrode test strip is provided, which includes an insulating substrate; an electrode system; an insulating layer that partially covers the electrode system so that one uncovered portion on the electrode system forms an electrochemical reaction region and another uncovered portion on the electrode system forms a conductive wire connecting region; and a reaction layer including an electron mediator and an anion surfactant and at least partially covering the electrochemical reaction region. A device for detecting hemoglobin is further provided, which includes the hemoglobin-detecting electrode test strip and an electrochemical sensor.
