The PlasmaQuant? MS Elite has been successfully used for the determination of trace impurities in pure 5N Gold. This work demonstrates the benefits of high sensitivity and iCRC interference management in routinely achieving the detection limits necessary to measure gold purity to five nines (5N). In fact, routinely achieving detection limits to determine contaminates in gold of six nines (6N) purity is not far out of reach and would only require slightly cleaner working conditions.

本文用硝酸分解镍钴锰酸锂、王水浸取石墨，ICP法测试锂离子电池正、负极材料的化学成分。结果表明，标准曲线浓度有高有低，用轴向、侧向和侧向扩展测量方式；线性拟合好，R=0.9998～0.99998，RSD小；样品能高低浓度一同测定。同一元素不同分析线的对比检测，平行样的检测，结果均非常相近，主成分标准点回测的回收率在98.4%～101.9之间，证明无光谱干扰，仪器运行稳定，结果准确可靠。样品检测结果符合产品质量要求。

本文用盐酸分解锂离子电池三元材料， ICP法同时测试其主成分Ni、Mn、Co、Li、Al和杂质成分Na、Ca、Mg、Fe、Cu。结果表明，标准曲线拟合好，R=0.9991～0.99998，RSD≤1.29%，低浓度范围从0.025～0.50mg/L，高浓度范围为50～300mg/L，样品成分含量从0.00001～53.6%，表征了ICP比AAS更适宜测该材料——既有高灵敏度又有宽线性范围，即轴向、轴向扩展、侧向、侧向扩展四种测量方式得到了充分的展示。
