固体样品在几千电子伏能量的一次离子束轰击下的二次离子发射,已被广泛地应用于微区元素和同位素组成分析。在很多情况下,它的发展仍然取决于能否获得适当的定量分析方法。鉴于矿物的绝缘性质,组份的复杂和存在离子群,最困难的还是在岩石学方面。 The secondary ion emission of a solid sample under ion beam bombardment of several thousands of electron volts has been widely applied to the analysis of micro-elemental and isotopic composition. In many cases, its development still depends on the availability of appropriate quantitative methods. In view of the nature of mineral insulation, the complexity of the components and the existence of ion clusters, the most difficult is still in petrology.
