Abstract
The orthogonal projection approach (OPA), a stepwise approach develope d for the determination of the number of compounds present in a multic omponent system, has been extended by including a step that allows the chromatographic and spectroscopic pure compound profiles to be determ ined. This is done using an alternating least-squares procedure. The i nitial estimations are the spectra selected in the first step of OPA. The performance of the OPA algorithm is compared with that of two wind ow-based self-modelling curve resolution approaches: evolving factor a nalysis (EFA) and window factor analysis (WFA).
