发展了一种利用激光电离正交飞行时间质谱仪系统同时检测所有金属和非金属元素的元素成像方法。仪器控制和数据处理由自主开发的程序实现。该系统能够同时检测金属和非金属元素，空间分辨率为50微米，最低检测下限为3×10~(-7)g/g(Li)，动态范围为7个数量级。此外，这项技术不需要定量分析的标准，可以成为一种强大而通用的元素成像工具。
An elemental imaging method using a laser ionization orthogonal time-of-flight mass spectrometer system was developed for the simultaneous detection of all metal and nonmetal elements. The instrument control and data processing were realized by self-developed programs. This system is capable of simultaneous detection of metal and nonmetal elements, with a spatial resolution of 50 mu m, the lowest detection limits of 3 x 10(-7) g/g (Li), and a dynamic range of 7 orders of magnitude. Moreover, this technique does not require standards for quantitative analysis and can be a powerful and versatile tool for elemental imaging.
