Standard Reference Materials: Preparation and Characterization of K-411 and K-412 Mineral Glasses for Microanalysis - SRM 470

摘要

The two mineral glasses in SRM 470, K-411 and K-412, were quantitatively analyzed for major constituents. The results of wet chemical analyses from two independent laboratories were in excellent agreement; therefore, these results were used for certification. Specimens were evaluated for micro- and macrohomogeneity with the electron microprobe by using random sampling and periodic integrator homogeneity trace techniques.
