| 摘 要： | 对石墨涂样检测 Cs2 BO2 离子条件下甘露醇对硼同位素测定的影响进行了研究 ,结果表明在甘露醇存在下 11B/ 10 B比值明显高于只有石墨存在时的比值。硼 -甘露醇络合物的形成可能改变了 Cs2 BO2 -石墨方法的电离和蒸发条件。

| Abstract: | WT5BZ]The effect of mannitol on isotopic measurement of boron based on Cs 2BO 2 ion with graphite loading has been studied. The result suggest the measured 11 B/ 10 B ratios in the presence of mannitol are significantly higher than in the loading graphite alone. The ionization and evaporation condition for Cs 2BO 2 graphite method may be changed by the formation of mannitol boron complex. |
