Sample interview questions: Have you ever worked with plasma-based laser-induced breakdown spectroscopy techniques? If so, can you provide examples?
Sample answer:
Yes, I have extensive experience working with plasma-based laser-induced breakdown spectroscopy (LIBS) techniques. One notable example of my work in this area involved using LIBS to analyze the composition of different materials. We utilized a high-energy laser to induce a plasma on the surface of the sample, which in turn emitted characteristic spectral lines. By analyzing the emitted light, we were able to determine the elemental composition of the material.
In another project, I collaborated with a team of researchers to investigate the application of LIBS in environmental monitoring. We used a portable LIBS system to analyze the composition of soil samples and identify any potential contaminants. The advantage of using plasma-based LIBS in this context was its ability to provide rapid, non-destructive, and in situ analysis, making it a valuable tool for field studies.
Furthermore, I have also applied plasma-based LIBS techniques in the field of industrial process monitoring. In collaboration with a manufacturing company, we developed a LIBS-based system for real-time monitoring of the composition of molten metal alloys. By analyzing the plasma emission during the LIBS process, we were able to detect and quantify the presence of impurities, ensuring the quality control of the alloys.
Additionally, I have experience with LIBS applications in the medical field. One project involved using plasma-based LIBS to analyze the elemental composition of biological tissues. By… Read full answer
