    摘要: A process for characterizing at least one sample comprising at least one substance (Si), in which at least one substance (Si) in the sample is identified and in which at least one quantity (Gji) which characterizes a substance (Si) in the sample is determined, at least the following process steps being carried out successively or simultaneously in an analytical centrifuging device: a) centrifuging the sample in an analytical centrifuge, b) exposing the sample to monochromatic light, preferably laser light, c) detecting light scattered by the sample, d) identifying at least one substance (Si) by a spectral evaluation of the inelastically scattered fraction of the scattered light which was detected in step c), e.g. by means of Raman scattering, and e) determining at least one quantity (Gji) for a substance (Si) by evaluating the state of the sample which it has entered as a consequence of the centrifuging in step a).
