LA-ICP-MS原位测定硫化物矿物微量元素的方法研究

Study on LA-ICP-MS Determination of Trace Elements in Sulfide Minerals

摘要:

利用New-Wave 193ss型193 nm激光器与Agilent 7500a型四级杆等离子体质谱仪联用的LA-ICP-MS系统，建立了一套原位硫化物矿物微量元素的测试方法。本实验采用单点剥蚀连续自动采集模式，采用美国国家调查局的玻璃标准物质NIST610为主标，对硫化物校准物质MASS-1进行测试，Si为外标物质的内标元素，分别选取Fe、Cu、Zn为盲样内标元素的双内标组方法进行数据处理，处理软件采用Glitter4.4.4。结果表明：综合选取两组内标Si-Fe和Si-Zn或Si-Cu和Si-Zn进行数据处理，硫化物校准物质MASS-1中已有推荐值的所有元素测试值与推荐值相对误差都在±20%以内，所有元素测试值相对标准偏差都优于10%，大部分元素优于5%。

Abstract: A method for in situ trace element analysis of sulfide minerals was established by using LA-ICP-MS, which combines the New-Wave 193ss type laser (193 nm) and the Agilent 7500a four-stage ICP-MS. In this study, the single point ablation and automatic continuous acquisition mode were used. The glass reference material NIST610 was used as the main standard, and the sulfide calibration mate-rial MASS-1 was tested. The analytical data were processed using the Glitter 4.4.4 software. Si was used as the internal standard for the external standard material. The double internal standard group method using Fe, Cu, Zn as the blind internal standard elements was used for data processing. By using Si-Fe and Si-Zn, or Si-Cu and Si-Zn as the internal standards, the results show that the errors between analytical results and the recommended values are better than 20%, the relative standard deviation of all elements is better than 10%, and most of the elements are better than 5%.
