Abstract
Abstract The invention relates to a sample arrangement for spectrometry, especially Raman spectrometry, with an essentially spherical sample container of transparent material, in the center of which the sample is arranged, and a procedure for the measurement of luminescence and scattering, e.g. chemiluminescence, fluorescence, phosphorescence and Raman scattering as well as absorption wherein the sample arrangement is placed in the optical paths of an in principle known spectrometer.
