ＧＰｔ＿１～７系列标准物质由土壤、水系沉积物、富镁超基性岩、富铁超基性岩、含铜镍贫铂矿石及铬铁矿等不同类型７个样品组成。铂族元素的含量范围从土壤和岩石的背景含量到矿石达４～５个数量级。经方差检验样品均匀度良好。标准物质的定值分析采用了不同类型的试金和湿化学法分离富集，以原子吸收、催化比色、催化极谱、等离子体质谱、发射光谱和中子活化等方法进行测定。定值的元素为Ｐｔ、Ｐｄ、Ｏｓ、Ｒｕ、Ｉｒ、Ｒｈ６个铂族元素及Ａｕ。该系列标准物质主要适于作铂族元素地球化学勘查和铂矿勘查中铂族元素分析的量值标准与测试的质量监控。
GPt_1 ~ 7 series of standard materials from the soil, sediments, magnesium-rich ultrabasic rocks, iron-rich ultrabasic rocks, copper-nickel-rich platinum ore and chromite and other different types of seven samples. Platinum group elements range from the background content of soil and rock ore to 4 to 5 orders of magnitude. Variance test sample uniformity is good. The determination of standard materials using different types of gold and wet chemical separation and enrichment, with atomic absorption, catalytic colorimetric, catalytic polarography, plasma mass spectrometry, emission spectroscopy and neutron activation and other methods were measured. The set values are Pt, Pd, Os, Ru, Ir, Rh6 platinum group elements and Au. This series of standard materials is mainly suitable for the quality control of the quality standards and tests for the analysis of the platinum group elements in the platinum group element geochemical exploration and platinum prospecting.
