Abstract

Applications of ICP-QMS/QMS using H2 as a reaction gas were investigated for the accurate and precise determination of Fe in glass fragments. The maximum signal to background ratio was calculated by dividing ion counts for the sample solution (50 ng mL-1 Fe in 0.8 mol L-1 HNO3) by that obtained for a blank solution (0.8 mol L-1 HNO3) at H2 gas ‰ow rates of 8 and 6 mL min-1 for m/z=54 and 56, respectively. The obtained values for 54Fe and 56Fe in a certiˆed reference glass material (NIST 612) under the optimized condition in the H2 gas mode showed a good match with the reference value (51±2 mg g-1) with a precision of <7.1 by RSD. The number of indistinguishable pairs among the 13 sheet glass samples manufactured using the same production line was limited to 12 of 78 by comparison of only Fe concentrations measured using the method developed herein, demonstrating the potential contribution of Fe analysis to enhanced evidence collection.
采用ICP-QMS/QMS与八极体反应池对同一生产线生产的汽车玻璃板材进行铁的定量分析
研究了以H2为反应气体的ICP-QMS/QMS对玻璃碎片中铁的精确测定。最大信本比是用样品溶液(50 ng mL-1 Fe在0.8 mol L-1 HNO3中)的离子计数除以空白溶液(0.8 mol L-1 HNO3)在H2气流速为8和6 mL min-1时(m/z=54和56)的离子计数计算得到的。在优化条件下,在H2气体模式下,在经过认证的参考玻璃材料(NIST 612)中得到的54Fe和56Fe值与参考值(51±2 mg g-1)吻合良好,RSD精度<7.1。在使用同一条生产线生产的13个平板玻璃样品中,仅通过使用本文开发的方法测量的铁浓度进行比较,无法区分的样品数量限制在78对中的12对,这表明铁分析对增强证据收集的潜在贡献。
