在微波辅助系统中对屑状的样品进行湿法消解,采用飞行时间电感耦合等离子体质谱测定钢、镍基合金及锆锡合金中9种痕量和超痕量元素元素。所建立的工作曲线的线性跨度达多个数量级。对一些稀有元素如Ga,Ta,Ir,Pt和,U和较常见的元素如Sn,Sb,Pb和Bi一起进行测定,检测的含量范围从0.046μg/g(锆锡合金中的U)至45μg/g(低合金钢中的Sn),并测定了镍基合金中的微量元素Sn。对于所分析的样品中μg/g级和次-μg/g级的元素,获得了较好的精密度和准确度。 Wet-digestion of the crumbed samples was performed in the microwave-assisted system, and time-of-flight inductively coupled plasma mass spectrometry was used to determine nine trace and ultra trace element elements in steels, nickel-base alloys and zirconium-tin alloys. The established working curve has a linear span of several orders of magnitude. Some of the rare elements such as Ga, Ta, Ir, Pt, and U are measured together with the more common elements such as Sn, Sb, Pb and Bi in an amount ranging from 0.046 μg / g (U in Zircaloy) to 45 μg / g (Sn in low-alloy steel), and the trace element Sn in the nickel-based alloy was measured. For the μg / g and sub-μg / g elements in the analyzed samples, better precision and accuracy were obtained.
