摘要：We prent new reference values for the NIST SRM 610–617 glass following ISO guidelines and the International Association of Geoanalysts' protocol. Uncertainties at the 95% confidence level (CL) have been determined for bulk- and micro-analytical purpos. In contrast to former compilation procedures, this approach delivers data that consider prent-day requirements of data quality. New analytical data and the nearly complete data t of the GeoReM databa were ud for this study. Dat
a quality was checked by the application of the Horwitz function and by a careful investigation of analytical procedures. We have determined quantitatively possible element inhomogeneities using different test portion mass of 1, 0.1 and 0.02μg. Although avoiding the rim region of the glass wafers, we found moderate inhomogeneities
