Micro-XRF spectrometry is a well-established method for the non-destructive elemental analysis of inhomogeneous materials. Its full potential for the analysis of biological samples, however, is just starting to be utilized.

Promising fields of application include the analysis of biomaterials, e.g. implants in their biological environment, toxicological studies of nanoparticles in organs and the distribution of metal-containing pharmaceuticals in thin tissue slices of human or animal origin. With its spatial resolution in the range of 20µm and ppm level sensitivity, Micro-XRF is perfectly well-suited to investigate elemental distributions at the tissue level. It also represents an ideal complimentary technique to other analytical methods in this segment, as for instance Laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS).

The Special Guest of this webinar will be Prof. Uwe Karst, Chair of Analytical Chemistry, University of Muenster. He is one of the first users utilizing tabletop Micro-XRF for bio-imaging applications. Prof. Karst will present some exciting examples of his work.

There will be a 15 minute Q&A session where our experts will answer your questions.

Who should attend:

  • Researchers working in bio imaging
  • XRF users interested in new applications of the method

Prof. Dr. Uwe Karst

Prof. Dr. Uwe Karst

Chair of Analytical Chemistry,
University of Münster


Uwe Karst obtained his Ph.D. in Analytical Chemistry at the University of Münster, Germany in 1993. He moved to the University of Colorado in Boulder, CO, USA as a postdoctoral research associate. After his return to the University of Münster, he finished his Habilitation in 1998. In 2001, he took over a position as Full Professor of Chemical Analysis at the University of Twente, The Netherlands. He accepted his current position as Chair of Analytical Chemistry at the University of Münster in 2005. His research interests focus on hyphenated analytical techniques and their (bio)medical and pharmaceutical applications, including elemental speciation analysis, metallomics, elemental and molecular bioimaging and electrochemistry/MS.
