    Abstract: The present disclosure concerns a method and detector (10) for detecting an analyte (1) in a sample volume (2), such as nitrosamine in an amine solvent. The method comprises measuring a resonance Raman spectrum (I1) with a first light beam (P1) matching an electronic transition of the analyte (1). The detection of the analyte is enhanced by measuring an off-resonance Raman spectrum (I2) using a second light beam (P2) that is shifted in wavelength at least 10 nm away from the electronic resonance. The resonance Raman signal (S1) of the analyte (1) is isolated from the background (Q1, Q2) by a difference analysis between the resonance and off-resonance Raman spectra (I1, I2). The method and detector (10) can be employed for detecting nitrosamine in a carbon capture process or plant (20) that employs an amine solvent.

    Abstract: Embodiments of the present invention provide a Raman spectroscopic inspection method, comprising the steps of: measuring a Raman spectrum of an object to be inspected successively to collect a plurality of Raman spectroscopic signals; superposing the plurality of Raman spectroscopic signals to form a superposition signal; filtering out a florescence interfering signal from the superposition signal; and identifying the object to be inspected on basis of the superposition signal from which the florescence interfering signal has been filtered out. By means of the above method, a desired Raman spectroscopic signal may be acquired by removing the interference caused by a florescence signal from a Raman spectroscopic inspection signal of the object. It may inspect correctly the characteristics of the Raman spectrum of the object so as to identify the object effectively.

    Abstract: The invention relates to a method and a device for producing and detecting a Raman spectrum. The problem addressed by the present invention is that of devising a method and a device for producing and detecting a Raman spectrum of a medium under investigation, whereby the Raman spectrum of a medium that is under investigation can be examined with a high degree of sensitivity while requiring relatively little equipment. The method is characterized by the coupling of excitation radiation into a medium (8) under investigation and the coupling of the electromagnetic radiation scattered by the medium (8) under investigation into a spectral optic system (10), a laser diode (1) for generating excitation radiation with at least two different wavelengths (λ1, λ2) being controlled with at least two different excitation conditions and at least one Raman spectrum (16, 17) being detected in each case from the scattered radiation at the different excitation wavelengths (λ1, λ2), and the Raman spectrum (20) of the medium (8) under investigation being determined from the at least two detected Raman spectra (16, 17), the two different excitation conditions for the laser diode (1) being adjusted by means of the electric current supplied to the laser diode (1).

    Abstract: A data set processing method for Raman spectroscopy systems using tunable lasers and multielement spectrometers compiles the spectral data set into an array and then estimates the background component, which is usually dominated by sample and optical train fluorescence, detector array dark current signal, fixed-pattern signal, and stray-light signals either modulated or non-modulated by in-path optics. This estimate is used as a baseline correction to the spectral data set to thereby isolate the sample's Raman response.

    Abstract: A source produces light, preferably in a wavelength band of approximately 185-200 nm and in pulses at a suitable frequency (e.g., 100 Hz). The light may be directed in a progressively diverging beam into the atmosphere for a Rayleigh scattering by molecules in the atmosphere in the 185-200 nm wavelength band and for fluorescence by particular molecules (e.g. oxygen) in the atmosphere in another wavelength band (e.g. 210-260 nm). The Rayleigh scattered light and the fluorescent light may pass in a progressively converging beam to two detectors, one responsive to the Rayleigh scattered light to produce first signals and the other responsive to the fluorescent light to produce second signals. Optical elements may prevent the second detector from responding to the fluorescent light and the second detector from responding to the scattered Rayleigh light. A data processor processes the first and second signals to provide outputs representative of the atmospheric pressure and temperature. These outputs may have a great accuracy, in part by regulating the characteristics of the light source and the first and second detectors at times between the successive light pulses from the source. The progressively diverging and progressively converging beams may have a focal point displaced externally of the housing by at least a particular distance to avoid effects of turbulence when the housing is in a moving vehicle.

    Abstract: A Raman spectroscopy device includes: an irradiator that irradiates a sample with first excitation light having a first line width and second excitation light having a line width broader than the first line width; a spectroscopy measurer that, when first measurement light emitted from the sample when the sample is irradiated with the first excitation light and second measurement light emitted from the sample when the sample is irradiated with the second excitation light are incident, performs spectroscopy measurement on the first measurement light and the second measurement light; and a first selective optical system that has a first transmission band and a first stop band, and filters the first measurement light and the second measurement light incident on the spectroscopy measurer. The first excitation light and the second excitation light each have a main component in the first stop band, and the second excitation light has substantially no component in the first transmission band.
