Abstract: A method for determining a vertical position of a horizontally extending interface between first and second components is presented. The first and second components are contained in a laboratory sample container in layers vertically separated from each other. The method comprises generating first data, generating second data in the form of picture data of the laboratory sample container containing the first and second components, determining a first probability distribution function in response to the first data, determining a second probability distribution function in response to the second data, and determining the vertical position of the horizontally extending interface depending on the first and second probability distribution functions. The first data depend on the vertical position of the horizontally extending interface. The first and second probability distribution functions assign a probability of the presence of the horizontally extending interface to a vertical position.

Abstract: A method for determining properties of a laboratory sample contained in a laboratory sample container is presented. The method comprises measuring projections of the laboratory sample container comprising the laboratory sample by irradiating light to the laboratory sample container at different projection angle and determining the properties by tomographic reconstruction based on the projections.
