Error minimization apparatus and method for real-time spectral deconvolution of chemical mixtures

摘要

An apparatus and method are described for determining the relative concentrations of the N constituent chemical components of a chemical combination. The spectral response, Ci, of the composite sample is measured at M wavelengths lambda i, wherein M>/=N. The relative concentration of the jth constituent is Xj. The spectral response of the jth component at wavelength lambda i is Aij. the set of M equations have intersections defining values of Xj of which only those within the region defined by 0
