From September 24 to 26, 2018, some members of the Fittschen working group participated in the 9th TXRF and µ-XRF Workshop at the Institute of Inorganic and Analytical Chemistry of the Westfälische Wilhems-Universität Münster. After lectures on the various applications of the methods, they were demonstrated on the second day during a laboratory day and there was the possibility to homogenize and investigate own samples. Further exciting application-related lectures followed on the third day.
