Cover Story: Unlike classical Liquid Chromatography, Centrifugal Partition Chromatography utilizes two immiscible liquids as the mobile and stationary phases. With centrifugal force, the latter is immobilized in the chambers of the apparatus, enabling repeated dispersion within the stationary phase and subsequent coalescence of the mobile phase. After sample injection, the chromatographic process takes place. This article showcases the utilization of camera technology and automated image analysis to determine the proportion of both phases in the apparatus quickly and reliably. These insights contribute decisively to the optimization of operating parameters, enabling long-term operation while simultaneously maximizing separation efficiency. View this paper
