Standard Test Method for Determination of Concentrations of Elements in Glass Samples Using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for Forensic Comparisons

Importancia y uso:

4.1 This technique is destructive, in that the glass fragments may need to be crushed, and digested in acid.

4.2 Although the concentration ranges of the calibration curves shown in Appendix X1 are applicable to soda lime and borosilicate glass, this method is useful for the accurate measurement of element concentrations from a wide variety of glass samples.

4.3 The determination of the element concentrations in glass yields data that can be used to compare fragments.

4.4 It should be recognized that the method measures the bulk concentration of the target elements. Any extraneous material present on the glass that is not removed before digestion can result in inaccurate concentrations of the measured elements.

4.5 The precision and accuracy of the method should be established in each laboratory that employs the method.
