From hair to body liquids - TXRF analysis of biological and medical samples

On-Demand Session - 42 Minutes

Analysis of Biological Samples with TXRF Spectroscopy

This one-hour webinar will demonstrate the use of Total reflection X-Ray Fluorescence (TXRF) spectroscopy in medical and biological research.

Today, the crucial role of trace element analysis is well recognized.

  • The distribution of micronutrients like Mg, K, Ca, Mn, Cu, Zn, Se, Mo and I gives information on diseases, metabolic disorders, environmental exposures, and nutritional status. 
  • As an excretory system, human hair can accumulate and incorporate toxic metals into its structure during its growth process. Therefore, concentrations of heavy metals in hair can reflect the mean level in the human body, recording the population’s exposure to heavy metals. 

For hair analysis as well as in biological and medical research TXRF spectroscopy offers a perfect technique for the fast and easy analysis of main and trace elements. These include elements like bromine or selenium, which are generally difficult to analyze with methods like ICP-MS. In most cases the samples can be analyzed directly or after a simple dilution or homogenization in pure water. The necessary amount of samples for a complete analysis is only restricted by the working range of the applied balances or pipettes and can go down to a few µg or µl.

During this webinar, you will find out more about element analysis of human hair samples. We will also talk about rapid sample preparation and the ease of use of this technique, as well as presenting several examples for the analysis of different biological and medical samples.

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

Who should attend?

  • Researchers of the biological and medical industry
  • Scientists, postdoctoral fellows, students at biological or medical institutes and research centers
  • Physicians and chemists at hospitals and clinical research facilities
  • Researchers in analytical chemistry with interest for new technologies and methods
