Abstract
An approach is proposed for recovering individual spectra of components in two-layer systems using the method of multivariate curve resolution–alternating least squares. The method is applicable to recording spectra in the near infrared region in both transmission and diffuse reflectance modes. The efficiency of the method is tested on a model system polymer film–polymer film and on real samples polymer packaging film–infinite layer of powdered product.
