摘要
本文描述了采用阴离子树脂珠作为质谱样品载体,胶体石墨加蔗糖-铼粉混合溶液为粘接剂,利用单带,对铀同位素分析进行研究,获金属离子,使仪器灵敏度比常规液体滴样方法提高2—3个量级。给出了样品量为4—6ng的天然铀同位素分析结果。
Using anion resin bead as a sample Carrier, colloid graphite and mixed solution of sucrose with rhenium powder as an adhesive, uranium isotope analysis was investigated in MAT-260 mass spectrometer with single filament. Metallic uranium ions were obtained. The sensitivity was 2—3 orders of magnitude higher than that of conventional method. The technique permits analysis of uranium on a single filament loading.
