SIMULTANEOUS ANALYSIS OF TWO-COMPONENT SYSTEMS BY DIFFUSE REFLECTANCE SPECTROSCOPY

Abstract
Diffuse reflectance spectroscopy can be used for the analysis of multicomponent systems in the adsorbed state. The Kubelka–Munk theory for diffuse reflection and transmission on light-scattering layers has been applied for this analysis. Simple dye mixtures adsorbed on thin-layer chromatography-grade adsorbents were employed. The method can be adapted directly to the analysis of incompletely separated components on chromatographic adsorbents.
