Abstract

In the last years Total Reflection X-Ray Fluorescence spectroscopy (TXRF) has shown to be an analytical technique for trace element analysis as well as surface quality control. Detection limits in the range of pg or ng/g (ppb) level in concentration values of aqueous solutions or 1011 -109 atoms/cm2 are achieved with new excitation sources. The range of detectable elements has been extended to low and high 2 elements. Instrumental developments and results of the Atominstitut as well as from some other working groups are presented.
