Contactless Chemical Analysis of Ternary Multicomponent Tablets by THz Sensing
Abstract: This article presents a contactless method for analyzing ternary mixtures in tablet form using THz sensing. By directly measuring the refractive index at absorption frequencies specific to maltose and glucose, the method enables accurate quantification without the need for uniform sample thickness or advanced chemometric modeling. Testing on 24 mixtures of polyethylene, maltose, and glucose shows that refractive index changes at characteristic peaks are proportional to the target compound's concentration. The findings suggest practical advantages for rapid, non-destructive analysis in industrial settings.
Keywords: THz time domain spectroscopy, ternary mixtures, sugars analysis, chemical composition, non-destructive testing
