建立了一种用同位素稀释快原子轰击质谱法测定食品中铁的方法。样品加入54Fe的浓缩源，用浓硝酸/硫酸消化，从6M HCl中提取的铁进入乙醚。对同位素比值测量的相对标准偏差(RSD)为1.30-4.49%，对铁的测量精度为1.26-6.44%。
A method employing isotope dilution fast atom bombardment mass spectrometry has been developed for the quantitative determination of iron in foods. Samples were spiked with an enriched source of 54Fe, digested with concentrated HNO3/H2SO4 and the iron extracted from 6 M HCl into diethyl ether. Bracketing procedures gave precisions ranging from 1.30-4.49% relative standard deviation (RSD) for isotope ratio measurements and 1.26-6.44% RSD for iron measurements.
