Standard Test Method for Determination of Trace Elements in Glass Samples Using Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
1.1 This test method covers a procedure for elemental analysis of magnesium (Mg), aluminum (Al, titanium (Ti), manganese (Mn), gallium (Ga), rubidium (Rb), strontium (Sr), zirconium (Zr), antimony (Sb), barium (Ba), lanthanum (La), cerium (Ce), samarium (Sm), hafnium (Hf) and lead (Pb) in the bulk of glass samples (irregularly shaped and as small as 200 micrograms) for the comparison of fragments of a known source to the recovered fragments from a questioned source. These elements are present in soda lime and borosilicate glass in ngg-1 to % levels. Alternative methods for the determination of elemental analysis of glass are listed in the references. This procedure may also be applicable to other elements, other types of glass, or other concentration ranges with appropriate modifications of the digestion procedure (if needed for full recovery of the additional elements) and the mass spectrometer conditions. The addition of calcium and potassium, for example, could be added to the list of analytes in a modified analysis scheme.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
