Abstract: The present invention relates to a method of determining a constituent of a sample and more specifically, to a method of correcting an absorbance value for a spectrometer. The method is especially applicable in connection with spectrometric analysis instruments for quantitatively determining the chemical composition of fluids, e.g. the content of fat, protein lactose or urea, in food products, especially in raw milk or dairy products. The method is based upon a measurement of one or more selected ranges of a spectrum, providing an absorption spectrum of the product. The method may be applicable in connection with all spectroscopic instruments giving rise to specific ranges of a spectrum, such as UV, VIS, NIR, IR, NMR, MS, etc.). Typically, the spectrum will be a MID-IR absorption spectrum.
