傅里叶变换质谱 (FT/MSR) 已被公认为是测定材料的元素组成和分子结构的强大分析技术。在傅里叶变换质谱仪中同时测量在单个事件中产生的所有物质提供了与脉冲激光的自然组合，其中脉冲激光用于烧蚀和电离样品的一部分。这种激光与 FTMS 的独特组合提供了来自无机和有机材料、表面层和块状材料的元素和分子信息。利用小激光光斑尺寸和用于在质谱仪内观察样品的光学系统，可以对材料进行微量分析，从而获得空间分辨的高分辨率质谱。回顾了 FTMS 的优点，并举例说明了激光探针 FTMS 的几个示例，以演示该技术在解决工业问题中的应用。
Fourier transform mass spectrometry (FT/MSR) has been recognized as a powerful analytical technique for the determination of elemental compositions and the molecular structure of materials. The simultaneous measurement of all species, produced in a single event, in a Fourier transform mass spectrometer provides a natural combination with pulsed lasers, where the pulsed laser is used to ablate and ionize a portion of a sample. This unique combination of lasers with FTMS provides elemental and molecular information from inorganic and organic materials and from surface layers and from bulk materials. Microanalysis of materials, allowing spatially-resolved high-resolution mass spectra to be obtained, is possible with small laser spot sizes and optical systems for viewing samples inside the mass spectrometer. The advantages of FTMS are reviewed, and several examples of laser probe FTMS are illustrated to demonstrate applications of the technique to industrial problem solving.
