采用ICP方法分析维生素矿物质

A vitamin mineral sample was presented to this laboratory for trace and major element determination. The sample was previously digested by microwave heating. The assay required was Zn,Fe, Cu, Mn, I2 at % levels and Pb, Cd, Hg, Al at ppm levels in the solid sample. This report gives the best wavelengths for the determination of analytes in these matrices, as well as the operating conditions and the analytical results. 高性能ICP光谱仪
