STUDY ON SYSTEM IDENTIFICATION OF LINEAR AND NON-LINEAR LIQUID CHROMATOGRAPHY SEPARATION

Abstract

The paper proposes the identification method of linear and non-linear chromatographic system. The non-linear isotherms and lumped mass transfer coefficients of chromatography separating sorbitol and mannitol are determined. And the theoretical elution curves calculated by non-linear chromatographic model are more accurate than those calculated by linear chromatographic model.

Keywords:

• Non-linear chromatography
• Separation
• System identification
