| 20120013889 | Method and Device for Determining the Position of a Boundary Between Two Phased in a Sample Tube - A method and device are provided for determining at least one vertical position of at least one horizontally extending interface between a first component and at least one second component present in a sample tube in layers separated from one another. To this end, the device exposes the sample tube in multiplex time to light impulses having a first and a second wavelength, measures intensities of light impulses of the first and second wavelength exiting the sample tube, and analyzes the measured intensities for determining the position of the interfaces. | 01-19-2012 |
