ICP法测定钢中微量Nb的技术分析

Technical Analysis of ICP Determination Minim Nb in Steel

本文叙述了应用ICP等离子光谱分析仪分析测定钢中微量铌,确定了创建该分析方法的相关条件。样品用含有氢氟酸的混合酸分解,在泵速120r/min、输出功率1150W、载气压力206.84kPa、辅助气流量:30L/h的条件下,分析简单快速,结果准确无误,为了测定钢中的微量铌,可取得满意的结果。

This text described the means of apply the ICP plasm spectrum instrument analyze minim Nb in steel made sure that the interrelated condition of found the analytical method. The sample uses the mixed acid that have hydrofluoric acid to decompose,Under the condition of pump rev is 120r/min,output power is l150W, the carry power is 206.84kPa, the assistant gas flux is 30L/h, Analyze terseness and celerity, result acoup sur,used for mensurate minim Nb in steel,can taking approving result.
