SYNCHROTRON X-RAY-FLUORESCENCE ANALYSIS OF GAS-BUBBLES IN GLASS

The use of synchrotron based x-ray microbeam fluorescence (mu-SYXRF) f or the identification of relatively insoluble gas species in bubbles i n glasses is presented. The nondestructive method of SYXRF allows the in situ analysis of unopened inclusions with high spatial resolution a nd low detection limits. The example is given of the analysis of the n oble gas Xe and Mo and Rb in an aluminosilicate glass matrix. The use of synchrotron based x-ray micro beam fluorescence for the nondestruct ive identification and analysis of fluid inclusions (gas bubbles) in g lasses is recommended for applications in the glass industry and geoch emistry of fluids.
