Multi-pumping flow systems exploit pulsed flows delivered by solenoid pumps. Their improved performance rely on the enhanced radial mass transport inherent to the pulsed flow, which is a consequence of the establishment of vortices thus a tendency towards turbulent mixing.This paper presents several evidences of turbulent mixing in relation to pulsed flows, such as recorded peak shape, establishment...
An automated procedure exploiting alkaline degradation of carbohydrates is proposed for spectrophotometric determination of total reducing sugars, TRS (hydrolyzed sucrose plus reducing sugars), in samples relevant to the sugar industry. An environmental friendly reagent is used instead of the commonly used toxic (e.g. arsenate) or expensive (e.g. enzymes) reagents. The analytical steps of acidic sucrose...
