应用

无铅焊锡焊料中Ag与Cu的分布

对无铅焊锡焊料中大量含有Ag的区域进行面分析的数据。(加速电压:10kV;照射电流:20nA)
Ag的X射线像中颗粒形状与BSE像(COM🐷PO)的颗粒形状一致。直径约0.1μ๊m的Ag颗粒也清晰可辨(红色虚线圈出)。同时可确认Cu颗粒的存在(黄色虚线圈出)。

 

生物体组织中的金属元素

以下数据为EPMA捕捉到的肿瘤细胞中铂(Pt)元素图像,通过靶向给药将抗肿瘤药物卡铂(铂络合物)导入小鼠头颈部肿瘤组织中后进行分析检测。
卡铂通过与癌细胞内的遗传因子DNA链结合,阻碍DNA的分裂(复制)以杀灭癌细胞,和记娱乐可以通过元素图像了解抗癌药物以何种形态🍷进入癌细ꦫ胞内。
