| Abstract Scope |
A novel optical cell has been developed for the measurement and characterization of vapor phase species, using a combination of UV-Vis, LIBS, and Raman spectroscopy. The optical cell is designed to contain vapor from a heated sample, with optical windows on the cell allowing access for spectroscopic probing. The cell is constructed of stainless steel and high-temperature components to allow for a maximum temperature of 450°C. Initial tests were conducted using naphthalene, a chemical with a low sublimation point. Initial tests were successful, with UV-Vis and LIBS signatures identified that were consistent with naphthalene. The naphthalene testing prompted design modifications, and further testing was conducted with a salt compound antimony chloride. Successful testing of naphthalene and antimony chloride demonstrated the functionality of the optical cell design for combination spectroscopic measurements. |
