Diet samples were collected by a duplicated portion study for an adult male in both Mito, Japan and Los Alamos, U.S.A. The ashed samples were analyzed with inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled atomic emission spectrometry (ICP-AES) for 22 elements. The trace and ultratrace elements, Ba, Mo, Ni, Co, Cd, Cs, Tl, Pb, Bi, Th, and U were determined by ICP-MS. The major and minor elements, Na, K, P, Ca, Mg, Fe, Zn, Mn, Al, Sr, and Cu were determined by ICP-AES. Accuracy and precision for some elements were examined by analyzing National Institute of Standards and Technology (formerly National Bureau of Standards) Standard Reference Materials, 1577b Bovine Liver, and 1573 Tomato Leaves. Simultaneous multielement analyses of diet samples by using the two methods were found to be very useful.
通过重复部分研究，分别在美国洛斯阿拉莫斯和日本水户采集了一名成年男性的饮食样本。对灰化后的样本采用电感耦合等离子体质谱法（ICP-MS）和电感耦合原子发射光谱法（ICP-AES）分析了22种元素。痕量和超痕量元素钡、钼、镍、钴、镉、铯、铊、铅、铋、钍和铀采用ICP-MS测定。常量和微量元素钠、钾、磷、钙、镁、铁、锌、锰、铝、锶和铜采用ICP-AES测定。通过分析美国国家标准与技术研究院（前身为国家标准局）的标准参考物质1577b牛肝和1573番茄叶，检验了部分元素的准确度和精密度。结果发现，使用这两种方法对饮食样本进行同步多元素分析非常有用。
