PIXE analysis of Kupferschiefer samples

Henryk Kucha, Wojciech Przybyłowicz, Józef Kajfosz, Stanisław Szymczyk


PIXE multielement analyses of Kupferschiefer samples have been performed. Thick target PIXE (TTPIXE) detection limits (MDLs) for different matrices are reported. The best MDLs were found in light matrices, i.e. in organic carbon (kerogen-thucholite) and black shale. The poorest results were obtained in sulphides. The adventage of using PIXE versus other methods relics on: (1) fast and non destructive determination of all elements starting from Z = 18 in the studied ease; (2) relatively low detection limits, in the order of ppm.
