Abstract: The proposed method is related to the field of technical physics, in particular, to spectral methods for determining the elemental composition of liquid media using an electric discharge in the liquid as a source of spectra. The method can be implemented in devices for determining elemental composition of liquid media. The areas of application include water treatment systems at public water supply facilities, nuclear and thermal power industries, chemical industry, food industry processes (for water quality control), environment monitoring, etc. The technical result of the invention is a higher stability and reproducibility of measurement results and a better long-term operation reliability of the device. The proposed method for emission analysis of elemental composition of liquid media includes initiation of a local electric discharge in the liquid under analysis with the formation of a current-carrying channel in the volume of a diaphragm opening made in a member of the electrolytic cell structure, and detection of the generated emission spectra of the chemical elements being determined. The result is obtained due to the fact that the elements being determined are first deposited in the current-conducting channel volume at a current insufficient for initiating a local electric discharge, then the current direction is changed and its magnitude is increased for initiating a local electric discharge, and the emission generated in the liquid being analyzed is detected as emission spectra of the elements being determined. The deposition current intensity can be selected according to elements to be determined and their concentration in the liquid.

Abstract: A non-invasive method for determining a concentration of a gas component in a gas mixture contained in a spacing of a glass unit having at least two glass sheets spaced apart from each other and forming said spacing. One or more light beams is applied at an angle to the surface of said glass unit, wherein the wavelength of the emitted light beam is varied around or over the at least one absorption line of the interest gas component. The light beams transmitted through or reflected from at least one surface or interface locating at the opposite side of the spacing are collected by a detector and non-linear variations in the intensity of the t transmitted or reflected light beams over an absorption line of the interest gas is then component determined. The concentration of the gas component to be measured is determined based on said non-linear variations in the intensity.

Abstract: The invention relates to a spectrometer (10), comprising a hollow main optical body (12) having at least one light channel (14), a light source (18), a diffraction grating (20) having a center grating point, a light inlet opening (24), and a detector unit (22), which are arranged in such a way that the focal curve of the spectrometer fills the back focus equation. In order to create a spectrometer having sufficient spectral resolution from a low-price, light, and easy-to-process material, said spectrometer being able to operate in a large temperature interval even without temperature stabilization, the light inlet opening (24) is arranged on a compensation body (28), the compensation body (28) is arranged in the light channel (14) and fastened to the main optical body (12) between the light source (18) and the diffraction grating (20), and the compensation body (28) is dimensioned in such a way that the compensation body changes the distance between the light inlet opening (24) and the center grating point when the main optical body (12) thermally expands.

Abstract: A sample analysis system comprises a laser unit and a spectrometer unit. The laser unit emits a first laser pulse and a second laser pulse towards the sample with a pulse separation time of between about 1 microsecond to 20 microseconds. The laser unit includes an oscillator unit which is configured to generate the first laser pulse and the second laser pulse. A pre-amplifier unit is configured to receive the first laser pulse and the second laser pulse and increase the energy levels of each pulse prior to the pulses being emitted from the laser unit. The spectrometer unit captures emissions generated by the sample after the sample is stuck by the first and second laser pulses and identifies the elemental constituents of the sample using the emissions.

Abstract: A spectroscopic measurement apparatus 1A comprises an integrating sphere 20 in which a sample S is located, a spectroscopic analyzer 30 dispersing the light to be measured from the sample S and obtaining a wavelength spectrum, and a data analyzer 50. The analyzer 50 includes an object range setting section which sets a first object range corresponding to excitation light and a second object range corresponding to light emission from the sample S in a wavelength spectrum, and a sample information analyzing section which determines a luminescence quantum yield of the sample S, determines a measurement value Φ 0 of the luminescence quantum yield from results of a reference measurement and a sample measurement, and determines, by using factors β, γ regarding stray light in the reference measurement, an analysis value Φ of the luminescence quantum yield with the effect of stray light reduced by Φ = βΦ 0 +γ. This realizes a spectroscopic measurement apparatus, a measurement method, and a measurement program which can reduce the effect of stray light generated in a spectrometer.
