Ablation chamber for a combination of LIBS and LA-ICP-MS techniques
Sovadina, Petr ; Kuchynka, Michaela (referee) ; Novotný, Jan (advisor)
Laser-induced breakdown spectroscopy (LIBS) and laser ablation inductively coupled plasma mass spectroscopy (LA-ICP-MS) are spectroscopic techniques that use a pulsed laser to ablate the material in their analysis. Although LA-ICP-MS can reach a much lower detection limit than LIBS, it is not able to detect elements of organic compounds, halogens, and noble gases. By combining these two spectroscopic techniques, it is possible to overcome these shortcomings, to analyze all elements with LIBS, and also to analyze with a lower detection limit with LA-ICP-MS. To perform this combination of spectroscopic techniques, it was necessary to design an ablation chamber that would simultaneously support both LIBS and LA-ICP-MS measurements. The design of the ablation chamber consists of the mechanical design, the simulation of the gas flow inside the chamber, and finally its fabrication and assembly.
