This paper is dealing with one of the applications of liquid chromatography using rotary disks. The research aims to study the effect of using distilled water (PH = 7) as a carrier phase and its absence on the practical results using NaOH and KOH at different speeds (2500, 3000, 3500 rpm). As well as choosing the best ratio of the diameter of the rotary disk nozzles that achieves the best displacement between the NaOH and KOH slides with paths separated from each other. Then propose a mathematical model that shows how the thickness of the slice sector behaves with changing the rotational speed. After that, calculating the pressure caused by the rotation and evaluating the results up to a speed of 12000 rpm. The practical results proved that the carrier fluid has an apparent effect on the displacement value between NaOH and KOH slides by changing the internal and external diameters of the rotating disk nozzles and the rotational speed from (500-3500 rpm). The effect of each of them was clear on the displacement of the injected slices from the center of the rotating disk and the convergence between the practical and theoretical results.
