Abstract
Method and apparatus for sensing fluid interface(s) in a complex fluid such as centrifuged blood, includes a sensing assembly with a microwave source and a microwave sensor positioned in spaced opposed relation, the microwave source and sensor defining a microwave propagation path. Relative motion is induced between the sample container and the microwave energy propagation path in the region between the source and sensor in a direction that intersects and is essentially perpendicular to the microwave energy propagation path; and processor apparatus responsive to the scanning apparatus and the modification in microwave energy sensed by the microwave sensor provides an indication(s) of the location(s) of a fluid interface(s) in the container.
