Multivariate curve resolution-alternating least squares (MCR-ALS) was applied to atomic emission data obtained from inductively coupled plasma-optical emission spectrometry analysis of boron for the quantification of B-10/B-11 ratios. The determination of isotopic composition of boron is based on the isotopic shift of B-10 and B-11 in the emission line of 208.957 nm. After recording of the emission spectra in the range of 208.940-208.970 nm, evaluation of isotopic composition of boron containing samples was performed with MCR-ALS algorithm. MCR-ALS was able to resolve the emission spectra of B-10 and B-11 mixtures. The performance of the proposed methods was tested by determination of B-10/B-11 ratios in synthetic mixtures and also water samples.
