【摘要】 本文介绍了用铝合金中主要元素铝作内标,对Si、Mg、Fe、Zn、Mn、Cu作定量分析的方法。考察了激光取样、辅助火花放电电压、电极尖端距离等条件变化时对分析结果的影响。试验结果表明,用铸造法配制的铝合金标样是可行的,方法的相对误差在14%以内,相对标准偏差小于10%。更多还原

【Abstract】 This paper describes a method for quantitative analysis of Si, Mg, Fe, Zn, Mn, Cu in aluminum alloy by using aluminum, a major element in aluminum alloy, as an internal standard. The influence of laser sampling, auxiliary spark discharge voltage, and electrode point gap on analytical results was examined. The relative error is within 14% and relative standard deviation is less than 10%.更多还原
