Abstract

A fluid separation device includes a centrifugal separator configured to receive a centrifugal separation chamber of a disposable fluid flow circuit, a pump system configured to convey a fluid into the centrifugal separation chamber and to remove a separated fluid component from the centrifugal separation chamber via an outlet, a color-based interface monitoring system configured to determine an interface position between separated fluid components continuously flowing through the centrifugal separation chamber based on dominant wavelength measurements of layers of separated fluid components during a centrifugal separation procedure, and a controller configured to measure the dominant wavelengths of the layers, calculate a duration as a color time for each measured dominant wavelength, set target color times, calculate error signals and calculate control signals to adjust the pump system to control the flow rate and interface position.
