SMART Chart Webinar Series: LIBS
Laser Induced Breakdown Spectroscopy (LIBS)
Let's take a deeper dive into our SMART Chart!
Laser micro-sampling is one of the most versatile chemical analysis approaches available today. Recent technological advances in laser induced breakdown spectroscopy (LIBS) have set this technique apart in the world of analytical chemistry, as it can uniquely provide 2D and 3D elemental distribution mapping of any element present in most solid materials down to 0.5-1 ppm, over areas hundreds of microns to tens of millimeters. LIBS is particularly useful for depth analysis as the laser can be re-focused on the same location of a sample surface and provide depth profiling at a resolution of 100’s of nanometers per pass, depending on the sample matrix.
LIBS combines automated laser micro-sampling with optical emission spectroscopy, allowing for in-direct but near-instantaneous measurement of materials. LIBS is particularly powerful for atmosphere sensitive samples, and are currently used on NASA’s Mars rovers.

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.
In this webinar we will cover:
- Overview of the principles of LIBS
- Examples of LIBS 2D and 3D mapping and statistical analysis of a diverse range of materials, including pharmaceuticals, glass, coated metal alloys and graphite
