提出了一种基于改进的激光电离正交飞行时间质谱仪的铁氧化物形态直接分析的新方法。获得时间分辨质谱用于研究由激光电离源产生的元素离子和氧化物离子。形态分析方法,包括识别的特征离子和使用的离子丰度比进行了评价的氧化物的分化。研究了操作参数对团簇离子分布的影响,并对其形成机理进行了讨论。
A novel method has been developed that allows the direct speciation analysis of iron oxides based on a modified laser ionization orthogonal time-of-flight mass spectrometer. Time resolved mass spectra were acquired for the investigation of elemental ions and oxide ions generated by a laser ionization source. Speciation methodologies, including the identification of characteristic ions and the use of ion abundance ratios were evaluated for the differentiation of the oxides. The influence of operating parameters on the distribution of cluster ions was investigated, and their mechanism of formation discussed.
