This award will support the development of comparative standard samples for the quantitative analysis of the element oxygen with the microanalytical electron probe technique. Although oxygen is the most abundant element on earth, its concentration in minerals and synthetic materials is usually inferred by making assumptions about charge balance and stoichiometry. The capability to directly analyze oxygen concentration on a microanalytical scale will constitute an important analytical advance in mineralogy and materials science.

该奖项将支持用微量分析电子探针技术对氧元素进行定量分析的比较标准样品的开发。虽然氧是地球上最丰富的元素，但它在矿物和合成材料中的浓度通常是通过对电荷平衡和化学计量学的假设来推断的。在微观分析尺度上直接分析氧浓度的能力将构成矿物学和材料科学分析的重要进展。
