Abstract

The present invention relates to a method for separating lymphocytes and/or stem cells from whole blood in an automated blood separation system, wherein the quality of the collected lymphocytes and/or stem cells fractions is increased and the cell collection procedure is further automated by use of an optical sensor comprised in a detector device to measure turbidity and colour in the claimed method and in a cell separator, which can be used to perform the claimed method. The method of the invention is particularly useful to collect lymphocytes and/or stem cells fractions from whole blood, wherein the contamination of the collected cell fractions by platelets, red blood cells and granulocytes is reduced.
