    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 ¦ 0 of the luminescence quantum yield from results of a reference measurement and a sample measurement, and determines, by using factors ², ³ regarding stray light in the reference measurement, an analysis value ¦ of the luminescence quantum yield with the effect of stray light reduced by ¦ = ²¦ 0 +³. 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.

    Abstract: An electrolysis device (1) comprising a cell (10) containing a solution (60), a pair of electrodes installed in the cell (10), and a voltage application device (50) connected to the pair of electrodes. One electrode of the pair of electrodes is a smaller electrode (20), and another electrode of the pair of electroeds is a larger electrode (30). An area of a liquid-contacting portion (21) of the smaller electrode (20) with the solution (60) is smaller than an area of a liquid-contacting portion of the larger electrode (30) with the solution (60). In a state in which the solution (60) is contained in the cell (10), only the solution (60) is present between the liquid-contacting portion (21) of the smaller electrode (20) and a liquid surface (61) of the solution (60) vertically above the liquid-contacting portion (21) of the smaller electrode (20).

    Abstract: The quantitative analysis method for analyzing the composition of materials of the invention is based on a functional relationship (curve Cσ) between line intensity and the concentration of the element in the material. The method comprises: obtaining characteristic parameters, selecting the spectral lines of neutral atoms and ions of the elements of interest, obtaining their atomic data; calculating, for the selected lines, a line crosssection; measuring line intensities; determining the concentrations of the elements of interest by means of fitting two graphs Cσ, one for neutral atoms and another for ions with a unit charge, the fitting being performed by means of an iterative algorithm which compares the experimental graphs with the curves Cσ calculated with a plasma model; calculating, for the data of the graphs Cσ, the product of line optical depth by Lorentzian width; evaluating, for the data of the graphs Cσ, a condition on the validity limit of the model, the datum for which the mentioned product is greater being eliminated if the condition is not complied with; repeating the three preceding steps until all data comply with the mentioned condition. The invention has the advantage of not requiring prior calibrations.
