摘要
Centrifuged material layer volumes are measured and quantified during centrifugation of the material layers contained in a sample tube in a centrifuge assembly, which sample tube is disposed on a centrifuge platen. The material layers in the sample tube are periodically illuminated during centrifugation by a pulsed light source which differentially excites one or more fluorescent dyes or stains which are admixed with the sample being analyzed. This kinetic procedure is particularly useful in performing differential blood cell and platelet counts. A fluorscent target reference device is positioned on the centrifuge platen along with a detectable platen position sensor. The centrifuge assembly includes a processor controller which receives information from the platen position sensor, and from the target reference device, and which controls operation of the light source.
