    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: This invention is within the technical field of corundum appraisal, and it involves an examination method to determine whether corundum has undergone beryllium diffusion treatment. Procedurally, a highly sensitive Raman spectrometer (S/N>10,000) is used to scan and examine the samples. The spectrometer is fitted with a tailor-made probe having a large facula and surface area. Specially developed software is then used to perform an intensity correction and a background elimination to obtain a specific Raman spectral range (250-120 cm-1) with the corrected intensity and a smooth baseline. The corrected and standardized Raman characteristic peak at 804 cm-1 (side-band) is used as a basis to determine whether the corundum has undergone beryllium diffusion treatment. This invention method has the advantages of being non-destructive, simple, fast, and practical. Also, it can accurately determine whether corundum has been treated.

    Abstract: An autofocus Raman spectrometer system includes a laser probe assembly, a microprocessor, adjustable stages and a driving means. The laser probe assembly includes an excitation means, a focusing optics provided to focus an excitation beam from the excitation means onto a sample and generate Raman scattering spectrum, a collection optics for collecting the Raman scattering spectrum, and a spectrographic detector for generating a Raman spectrum based on the Raman scattering intensity received from the collection optics. The microprocessor receives the Raman spectra signal therefrom. The laser probe assembly is situated on the adjustable stage. The driving means is coupled to the microprocessor and configured to drive the stage to move with respect to the sample. The microprocessor generates a command to the driving means for moving a position of the adjustable stage to achieve an optimal optical focus based on signal intensity of the spectra peaks measured by the spectrographic detector.
