提出了一种利用流动注射同位素稀释电感耦合等离子体质谱测定地质样品中钐的方法。在采样体积为 3 0 0 μL的条件下 ,该法灵敏度较连续雾化进样提高了近 4倍 ,分析速度为 60样 min ,检出限为 0 4 2 μg L。
A method for determination of samarium in geological samples by flow injection isotope dilution inductively coupled plasma mass spectrometry was proposed. Under the condition of a sample volume of 3000 μL, the sensitivity of this method is nearly 4 times higher than that of the continuous atomization, and the analysis speed is 60 samples with the detection limit of 0 42 μg L.
