Elemental Analysis using XRF@headingTag>
Find out what elements are in your samples at the Nebraska Center for Materials and Nanoscience (NCMN) on the UNL campus. Students are able to meet with scientists to determine the elemental composition. The XRF uses a palladium source of radiation to excite the electrons and measures the energy emitted as electrons move between valences. This transition energy is special for each element. This method can detect elements between fluorine and uranium on the periodic table.
- How will metals content of soil affect the metals found in vegetables?
- Students are encouraged to develop their own hypothesis if they are interested in a different topic.
- Collect samples and send them to the NCMN for preparation
- Meet with scientists either in-person or online to process their samples and discuss the results
Lab skills learned:
- Sample collection and preparation
- How does XRF work
- What is Bragg's Law
