    Abstract: A transmission spectroscopy device can direct light into a sample, and determine properties of the sample based on how much light emerges from the sample. The device can use a cell to contain the sample, so that the size of the cell defines the optical path length traversed by light in the sample. To ensure accuracy in the measurements, it is beneficial to calibrate the device by measuring the size of the cell periodically or as needed. To measure the size of the cell, the device can perform a transmission spectroscopy measurement of a known substance, such as pure water, to produce a measured absorbance spectrum of the known substance. The device can subtract a known absorbance spectrum of the known substance from the measured absorbance spectrum to form an oscillatory fringe pattern. The device can determine the size of the cell from a period of the fringe pattern.

    Abstract: Method for calibrating an infrared spectroscopy apparatus to produce spectra to determine the concentration of a component C1 in one fluid F1 of an animal, includes: a) obtaining samples of fluid F1 and of a different fluid from each animal belonging to a group of representative animals, fluid F2 containing detectable amounts of at least one component C2 which is directly or indirectly related to a metabolic pathway of component C1; b) measuring the concentration of component C1 in the samples of fluid F1; c) producing the complete IR absorption spectrum of the samples of fluid F2; d) identifying in the absorption spectra of fluid F2 samples the spectral ranges that correlate with the concentration of component C1 in fluid F1 samples; and e) calculating, on the basis of at least one of the correlating spectral ranges, a predictive mathematical model of the concentration of component C1 in fluid F1.
