This book was released on 1991 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instrumental neutron activation analysis (INAA) and cyclic INAA (CINAA) techniques were used for the discrimination of flat glass fragments. Employing short irradiation, delay, and count times, sample test portions of 100 μg and 1 mg (INAA) or 1 and 5 mg (CINAA) were considered. A statistical model was used to assign the elemental variation among glasses to different experimental factors; by advanced statistical methods elemental differences between specific glasses can be identified. Analysis and comparison of float glass panes produced by two major Canadian manufacturers were also performed; the two were readily differentiated, primarily on the basis of their aluminum levels.
