| Popis: |
In 1990, the Institute of Geophysical and Geochemical Exploration prepared a series of certified reference materials of synthetic silicates and limestones. The silicate series (GSES I*) is composed of 11 samples with 28 ingredient elements and the limestone series (GSES II*) is composed 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 laboratories with various reliable methods and then certified values were derived. |
