چکیده انگلیسی
Closed-loop recycling countercurrent chromatography (CLR CCC) with multiple sample injection has been shown to provide simultaneous concentration and separation of target compounds from multicomponent mixtures. Previous analysis of CLR CCC with multiple sample injections has been limited to the ideal recycling model, which neglects the effects caused by the pump and connecting lines. In this study, an analysis of the process is carried out based on the non-ideal recycling model: recycling chromatograms at two points of the closed-loop - the inlet of the column (A) and the outlet of the column (B) - are considered. The sample is repeatedly introduced at the inlet of the column when the circulating peak of target compound passes point A. Analytical expressions are developed, allowing the design and simulation of different variants of simultaneous separation and concentration of target compounds from multicomponent mixtures. Examples of separation of target compounds from three and five-component mixtures are discussed. Experimental results are presented demonstrating a reasonable agreement between the theory and the experiment. Due to its ability to concentrate individual solutes, CRL CCC with multiple sample injections can become an efficient analytical method to determine minor components in complex mixtures.
