title: Development and Validation of Simultaneous Analysis of Minerals and Toxic Elements in Foods by ICP-MS.
abstract: We have developed and validated an inductively coupled plasma-mass spectrometry (ICP-MS) method for the simultaneous analysis of minerals and toxic elements in foods. Food samples were digested by microwave irradiation to prepare solutions for measurement by ICP-MS. Optimal gas mode and internal standard for each element were selected as appropriate. The method was validated for eighteen elements in total using three certified standard reference materials, namely, Typical Japanese Diet, Rice Flour-Unpolished and Infant/Adult Nutritional Formula, according to the guidelines of the Ministry of Health, Labour and Welfare of Japan. The trueness and precision of the method were all within the acceptable limits, except for Na in Rice Flour-Unpolished.
