Vacuum Ampoule Isolates Corrosive MaterialsQuartz vacuum ampoule confines corrosive sample wafer between two quartz plugs inserted in quartz tube. One quartz plug is window for measuring sample thermodynamic properties while laser pulse entering other quartz plug heats sample to molten state. Confinement of sample in vacuum prevents contamination of measurement system by hot corrosive vapors and any interference by preferential evaporation of melt.
