Trace and Ultra-trace Elemental Analysis of Advanced Materials by Direct Solid-Sampling and Solution-Based Techniques
Which should you choose?
Trace and ultra-trace level elements are defined as elements present in a material at concentrations below 100 ppm weight or 1x1020 atoms/cm2.
The type, concentration and spatial distribution of trace elements are of particular concern to many advanced technologies, including but not limited to advanced metal alloys and ceramics, sputter targets, semiconductors, optics, medical devices, pharmaceuticals, batteries, sensors, catalysts, in additive manufacturing, in electronics, in aerospace, in nuclear energy industry, and in quantum computing. The success of these technologies and industries relies on the high purity feedstock (e.g., 99.995% + purity) and contamination-free processing and engineering. Trace elements are also purposefully added as dopants in some materials, but often with strict controls on the maximum and minimum levels. They play a variety of roles, affecting the performance, the reliability and the lifetime of many materials, parts and devices, particularly under dynamic load, extreme environment or harsh conditions.
Characterizing the levels and distribution of such small concentrations of an element can be analytically challenging and selecting the most appropriate technique for your material or a specific element requires understanding of the relative limitations and advantages of the many different analytical techniques available.

About the Presenter:
Carys Falco (née Cook), Ph.D. is a Scientist and a technical leader of laser-based analytical techniques such as LIBS and LA-ICP-MS at Eurofins EAG Materials Science. Carys has over a decade of academic and contract-lab experience in advanced inorganic chemistry. She joined EAG in August 2017, after completing a two-year post-doctoral research position in ultra-trace radiogenic isotope analysis at the University of Florida. She received her M.S. from Cardiff University in Wales, and her Ph.D. from Imperial College London in 2013. She also sailed as a marine geologist on a research expedition to West Antarctica with the British Antarctic Survey. Her research publications have been cited in over 20 different Science and Nature papers, and has been interviewed by Time, Science Magazine and National Geographic for her research on climate change.
