摘要
电感偶合等离子体质谱ICP-MS是一种新型的无机元素和同位素分析技术,可迅速同时检测周期表上几乎所有元素。地层样品中的微量元素,有线性相关的,有多组相关的。这样分组计算既不方便,又不直观;如果把这些数据做成折线图,再加上方便的增、删功能,就可以轻松地"看"出他们之间的大致关系,快速轻松地解决问题,而且不需要复杂的计算过程。目前已有一些软件已能做出一部分,如电子表格等软件。但他们没有方便的即删即加功能,操作起来比较繁琐,而且数值差距较大时,便无能为力。本文以ICP-MS数据为例,探讨在VB下调用数据库直接绘图,增、删方便的功能可以有效节约时间,分数量级成图为多组数据相关提供了直观的对照,最终成图的结果较理想。
As an advanced detectable instrument, inductively coupled plasma-mass spectroscopy （ICP-MS） can detect almost all the elements in the Periodic Table. Some trace elements in the geological sample are correlative. Sometime the correlativity is linear, but in many times the correlativity is correlativity. Therefore, it is very difficult to estimate the correlativity among the data by using the traditional method. However, the graph, which is drawn basing on the data, can show the rough correlativity. And super adding some convenient function on the graph such as add and delete, estimating the correlativity also very fast and easy. In addition, there is not complicated calculating during this course. Some software, such as Microsoft Excel, can draw such diagram now. However, there are some disadvantages in that kind of software, such as complicated in manipulative process and without the function that the diagram can momentarily change with the data changing. Especially, if the algebraic is a large data, that kind of software cannot achieve. In this paper, using the database straight draw the diagram base on VB （ Visual Basic） to analyze the ICP-MS data, the function that the diagram momentarily change can be achieved.
