Environmental Trace-Element Analysis Using a Benchtop Total Reflection X-Ray Fluorescence Spectrometer
Rontec AG, Schwarzschildstrasse 12, D-12489 Berlin, Germany
Total reflection X-ray fluorescence (TXRF) analysis is an established technique for trace-element analysis in various types of samples. Though expensive large-scale systems restricted the applications in the past, in this study the capability of a benchtop system for trace elemental analysis is reported. The suitability of this system for the mobile on-site analysis of heavy metal contaminated soils and sediments is reported as well as the possibilities and restrictions of TXRF for additional applications, including trace-element analysis of water, glass and biological samples.
