Notes:
The rotating spectrometer is discussed as a method to separate and concentrate microorganisms in free solution. Following focusing in a rotated frame, the separation is accomplished using different radial dependencies of concentrated algal and protozoan species. The focusing itself appears as concentric rings and arises from the coupling between swimming direction and Coriolis forces. A dense cut is taken at varying radii and extraction is replenished at an inlet. Unlike standard separation and concentrating techniques, the rotating method requires active organism participation and, in principle, can split different morphologies and swimming behaviors for the large class of organisms known to bioconvect.
