產(chǎn)品詳細(xì)介紹
NBS28Quarz Sand Mineral 18O and 30Si
NBS-28 serves as the primary refence material (primary calibrator) for silicon δ29Si- δ30Si measurements defining the zero point of the δ-scale [1,2] and its 30Si//29Si/28Si ratios. In addition, NBS-28 serves as the refence material for δ18O in silicates.
Quartz sand for preparing NBS 28 was obtained by I. Friedman, U.S. Geological Survey from Corning Glass Company as. It was washed with acid to remove impurities and the fraction between 100 μm and 177 μm was separated and packed in 0.5 g units.
