A method for the simultaneous determination of arsenobetaine, arsenite, arsenate, dimethylarsinic acid, monomethylarsonic acid, selenite, selenate, bromate, bromide, iodate, and iodide in bottled drinking water and fruit juice samples was established by using high-performance liquid chromatography–inductively coupled plasma mass spectrometry. The separation of eleven compounds was performed on an ion exchange chromatography column (Dionex IonPac AS14) with 20 mmol L⁻¹ (NH₄)₂CO₃ (pH 10) and 50 mmol L⁻¹ (NH₄)₂CO₃ (pH 10) as a mobile phase. The limits of quantification of the method were 0.17 – 1.2 μg L⁻¹ for the test compounds in bottled drinking water and 0.34 – 2.4 μg L⁻¹ in fruit juice. The average recoveries ranged from 85.8 to 102.2%, and the relative standard deviations (RSDs) obtained in fortification recovery studies were generally <4.2% for bottled drinking water samples. The average recoveries ranged from 88.1 to 118.0% (except for iodate) for fruit juice sample.

建立了一种同时测定瓶装饮用水和果汁样品中砷甜菜碱、亚砷酸盐、二甲基砷酸、一甲基砷酸、亚硒酸盐、硒酸盐、溴酸盐、溴化物、碘酸盐和碘化物的方法，采用高效液相色谱-感应法同时测定。耦合等离子体质谱。在离子交换色谱柱 (Dionex IonPac AS14) 上使用 20 mmol L ^-1 (NH ₄ ) ₂ CO ₃ (pH 10) 和 50 mmol L ^-1 (NH ₄ ) ₂ CO ₃ (pH 10) 作为流动相。该方法的定量限为 0.17 – 1.2 μg L ^-1瓶装饮用水中的测试化合物和果汁中的0.34 – 2.4 μg L ^-1。平均回收率范围为 85.8% 至 102.2%，在强化回收率研究中获得的相对标准偏差 (RSD) 通常小于 4.2% 的瓶装饮用水样品。果汁样品的平均回收率为 88.1% 至 118.0%（碘酸盐除外）。
