Patent number: 11940326Abstract: A spectroscopic analysis device includes: a film that contacts a sample subject to spectroscopic analysis; a first irradiator that irradiates a first irradiation light having transition energy to decompose attached material attached to a boundary surface of the film; and an optical waveguide that transmits the first irradiation light irradiated from the first irradiator. A first evanescent wave, based on the first irradiation light, is generated on a front surface of the optical waveguide, and is then projected on an attached region of the attached material.Type: GrantFiled: August 19, 2021Date of Patent: March 26, 2024Assignee: Yokogawa Electric CorporationInventors: Kodai Murayama, Toshiyuki Saruya, Fumie Watanabe, Risa Hara

Patent number: 11821835Abstract: A spectroscopic analysis device includes a detector and a processor. The detector detects measurement light obtained by irradiating, with irradiation light, a sample that contains a contained substance disposed on a film on which surface plasmons are generated. The measurement light includes information on an optical spectrum of the sample, and the information includes a resonance spectrum of the surface plasmons and an absorption spectrum of the sample. The processor calculates: a peak wavelength in a wavelength band in which the resonance spectrum and the absorption spectrum are generated; a peak absorbance of the contained substance based on an absorption band of the contained substance; and a ratio of the contained substance to the sample based on the peak wavelength and the peak absorbance.Type: GrantFiled: March 31, 2021Date of Patent: November 21, 2023Assignee: Yokogawa Electric CorporationInventors: Risa Hara, Toshiyuki Saruya, Kodai Murayama, Fumie Watanabe
