Abstract:
Systems and methods of the present disclosure are directed to detecting species within a fluid using a multi-pass absorption cell and a spectrometer. The absorption cell includes a plurality of mirrors arranged in a manner such that a detection light traverses multiple passes through the fluid within the absorption cell. In some implementations, the detection light is reflected by the plurality of mirrors to form optical paths in more than one plane. The system also includes an electronic unit configured to receive and process spectral data from the spectrometer. In some implementations, the electronic unit communicates with at least one computational unit over a communication interface to send a portion of the spectral data for processing. The electronic unit may also receive processed data from the computational unit.
Abstract:
A gas analysis device includes a probe tube, a flange, an optical system member, and heaters. The probe tube includes an optical path through which measurement light is projected onto a prescribed measurement region of a sample gas flowing through a flue and/or is received from the measurement region. The flange is fixed to the outer periphery of the probe tube and is attached to a pipe side wall. The optical system member projects measurement light onto the sample gas S within the measurement region and/or receives measurement light from the measurement region. The heaters are disposed within the flange and heats the portion where the probe tube and flange are fixed to each other.
Abstract:
A spectroscopic device includes a lamp house accommodating a light source inside, a spectrometer configured to disperse light from the lamp house, a temperature measurement means for measuring a temperature of the spectrometer, a heating means for heating the spectrometer, a storage means and a control unit. The storage means stores the detection temperature of the temperature measurement means at a time when an optical axis is stable in the spectrometer in a state where the light source is illuminated. The control unit is configured to control operation of the heating means, and to cause the heating means to operate, when the light source is illuminated from a light-off state, until a detection temperature of the temperature measurement means reaches the detection temperature stored in the storage means.

Abstract:
This detection device has a holder and a heating unit. The holder holds a detection chip that has the following: a prism that has an incidence surface and a film-formation surface; a metal film formed on said film-formation surface; trapping bodies laid out on the surface of said metal film; and a substrate that is laid out on the surface of the metal film, and together with the metal film, forms a liquid collection section in which a liquid is collected. The heating unit heats at least one of the substrate, the prism, and the metal film either while in contact therewith or without contacting same. Also, the heating unit is positioned so as to avoid the path that excitation light takes from an excitation-light emission unit to the abovementioned incidence surface.

A laser device to be used in such optical analyzer is also provided. An optical analyzer comprises a laser light source (2); a wavelength selection element (3) for selecting and leading out light having a wavelength substantially equal to the absorption wavelength of an analysis object from among light outputted from the laser light source (2); an optical detection means (5) for detecting the intensity of light red out from the wavelength selection element (3); and a drive current control means (6) for increasing or decreasing the drive current of the laser light source (2) near a specified current value thereof for outputting light of the absorption wavelength, and setting the drive current at such a current value as the intensity of light detected by the optical detection means (5) has a peak value. The laser light source (2), the wavelength selection element (3), and the optical detection means (5) are mounted on a single substrate (11) which can regulate the temperature to a constant level.
