Abstract:  The influence of the height, position, and half-band width of the band of a component unconsidered in the calibration on the precision of the spectrophotometric determination of the other component concentrations in the sample was studied. The concentrations of the components being determined were computed by solving an overdetermined system of linear equations by the method of least squares. The study was performed with a three-component model system, the spectrum of which was approximated by the Lorentz functions.
