A method for determining an elemental composition of a material (1), comprising: a) conveying the material (1), b) analyzing the material (1) conveyed according to step a) by means of laser induced breakdown spectroscopy, LIBS, and / or by means of X-ray fluorescence analysis, XRF, c) Analyzing the material (1) conveyed in accordance with step a) by means of Prompter Gamma Neutron Activation Analysis, PGNAA, and / or Pulsed Fast Neutron Activation Analysis, PFTNA, d) Determining the elemental composition of the material (1) on the basis of the results from steps b) and c). With the devices (2, 9, 11) and methods described, the elemental composition in a material (1) can be determined with a particularly high measurement accuracy by applying PGNAA, PFTNA and / or LIBS to a material (1) in or on a conveyor (3) is applied. |
