Lakustrine Sedimente der Laguna de Fuente de Piedra: Ein Vergleich von zwei RFA-Messgeräten mittels statistischer Parameter

Abstract

The geochemical element analysis is an important part of the examination of lacustrine sediments for paleoclimatic reconstructions. X-ray fluorescence analysis is thereby one of the most important methods. Generally, stationary measuring devices are used, but nowadays cost-effective, portable instruments are used more and more. Subject of this work is the comparison of the high-resolution stationary ITRAX core scanner with the portable, allterrain Niton XLt 700 series environmental analyzer. Lake sediments from Laguna de Fuente de Piedra (southern Spain) form the data basis. Statistical parameters were calculated from the results of both X-ray fluorescence analyses and used to compare the data. The examination of these results displays that the measured element concentrations of the two devices show significant differences, but nevertheless there is a good correlation of the data series.
