Comparison of Window Glasses by Isotope Dilution Spark Source Mass Spectrometry
Comparison of glass fragments in forensic work is commonly done by measurements of refractive index and density. These methods are particularly well-suited for flat glass such as in windows. Further differentiation has been shown feasible by elemental analysis. Neutron activation analysis (NAA) , spark source mass spectrometry (SSMS) , and energy-dispersive X-ray fluorescence (EDX)  have all been successful in differentiating window glasses having identical physical properties.
