Abstract

An X-ray fluorescence measurement device comprises an X-ray source and a sample window for allowing X-rays from the X-ray source reach a sample. A filter arrangement between the X-ray source and the sample window includes a first filter layer comprising a first filtering element and a second filter layer including a second filtering element. The atomic number of the second filtering element is greater than the atomic number of the first filtering element. The first filter layer is between the X-ray source and the second filter layer.
