Abstract: A spectral analysis method for thermodynamically analyzing performs multivariate analysis to a plurality of measurement spectra measured under a plurality of measurement parameters, using MCR method that separates a pure spectrum from the plurality of measurement spectra, and calculates a concentration value of each pure spectrum. In this method, an equilibrium model corresponding to an equilibrium state of a sample in which three or more types of chemical species coexist is set, and at least one chemical-equilibrium equation corresponding to the equilibrium model is set. In the MCR method, a concentration curve based on the chemical-equilibrium equation is fitted to the calculated concentration values, an optimal value of a thermodynamic parameter is acquired, a new concentration value is acquired from the chemical-equilibrium equation based on the optimal value, and thus the concentration value is constrained.

Abstract: A light emitting apparatus has light emitting units. The light emitting units can be respectively provided with current densities, so that the light emitted by each of the light emitting unit has a light intensity, wherein the current densities are different from each other, or partial of the current densities are different from each other. A number of the light emitting units can be larger than or equal to four, all of the four lighting frequencies of the four light emitting units are different from each other, or partial of the four lighting frequencies of the four light emitting units are identical to each other, and the light emitting apparatus and the object under test rotate relative to each other. A light emitting method, a spectrum detection method and a lighting correction method are also illustrated for increasing SNR, correcting the light intensity or the spectrum signal.

Abstract: A blood sample collector can be used to collect a blood sample from a subject. The blood sample collector can be placed in a receptacle of a spectrometer to measure spectral data from the blood sample while the blood sample separates. The container may comprise a window to allow light such as infrared light to pass through the container, with the blood sample at least partially separating within the container between spectral measurements, which can provide improved accuracy of the measurements and additional information regarding the sample. The container may comprise an elongate axis and the container configured for placement in the spectrometer receptacle with the elongate axis extending toward a vertical direction in order to improve gravimetric separation of the blood sample. The spectrometer can be configured to measure the blood sample at a plurality of heights along the sample as the sample separates.
