Cs. Wang et al., CHINESE SYNTHETIC SILICATE AND LIMESTONE CERTIFIED REFERENCE MATERIALS FOR SPECTRAL-ANALYSIS, Geostandards newsletter, 20(1), 1996, pp. 57-64
In 1990, the Institute of Geophysical and Geochemical Exploration prep
ared a series of certified reference materials of synthetic silicates
and limestones, The silicate series (GSES I) is composed of ii sample
s with 28 ingredient elements and the limestone series (GSES II) is c
omposed of 9 samples with 29 ingredient elements. The standard series
were prepared in ascending element concentration order of 1, 2 and 5.
The synthetic standards were analyzed by a large number of laboratorie
s with various reliable methods and then certified values were derived
.
