    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: According to various embodiments, systems and methods for determining carbon dioxide detection in arthropods. An embodiment may include determining at least one resonant frequency of an arthropod sensory organ and an absorption spectrum of at least one odorant. A frequency filter may be applied to the absorption spectrum to eliminate frequencies below a given intensity value. Of the frequencies remaining from the absorption spectrum, those frequencies corresponding to relative peaks in absorption intensity may be selected. An olfactory chord including a group of the selected frequencies corresponding to the relative peaks in absorption intensity with at least one specific frequency that matches the at least one resonant frequency of the arthropod sensory organ. Additionally, at least one radiation source may be configured to emit electromagnetic radiation corresponding to the olfactory chord.

    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.

    Abstract: A measurement system configured to examine a sample. The system comprises an internally reflective element, a contact member, an actuator, an optical assembly, a sensor, and a controller. The contact member and the reflective element are configured to apply a force to the sample. The optical assembly is configured to scan the sample. Whereby prior to the scan, an initial force is applied to the sample, and after the scan, a resulting force is applied to the sample. The sensor is configured to detect the resulting force applied to the sample, and the controller is configured to receive a signal from the sensor indicative of the detected resulting force. The controller is further configured to control the actuator to adjust the force applied to the sample by the contact member and the internally reflective element from the resulting force to the initial force.
