Annotation

SPARK SOURCE MASS SPECTROMETRY IS USED TO DIVIDE A GROUP OF TWENTY WINDOW GLASS SAMPLES INDISTINGUISHABLE ON THE BASIS OF REFRACTIVE INDEX AND DENSITY.

Abstract

THE GROUP OF GLASSES CHOSEN HAD VALUES OF THESE PARAMETERS IN THE RANGE OF MODERN MASS PRODUCTION WINDOW GLASS WHERE CHANGES IN TRACE ELEMENTS MIGHT, IN VIEW OF THE MANUFACTURING PROCESS, BE EXPECTED TO BE SMALLEST. NOT LEAST IN IMPORTANCE WAS THE FACT THAT IN NINETEEN OF THE GLASSES THE TRACE ELEMENTS WERE SUCH AS TO CONFIRM THAT THE GLASS WAS IN FACT MODERN PRODUCED WINDOW GLASS AND NOT VEHICLE OR CONTAINER GLASS. THESE RESULTS INDICATE THAT THE APPLICATION OF TRACE ELEMENT ANALYSIS WOULD BE OF VALUE IN PROVIDING AN INCREASED DISCRIMINATION IN THE FORENSIC EXAMINATION OF GLASS SAMPLES. (AUTHOR ABSTRACT)
