Abstract :
The determination of trace elements in shellfish tissue samples by inductively coupled plasma mass spectrometry (ICP-MS) has been investigated. After determination of major and minor inorganic elements by ICP atomic emission spectrometry (AES), the internal standardization was discussed as a correction method for matrix effects in ICP-MS. The results obtained by quadrupole (Q)-ICP-MS after acid digestion almost agreed well with reported values. The high resolution (HR)-ICP-MS technique was applied to the determinations of V, Cr, Co, Ni and As in order to remove the mass spectral overlapping caused by polyatomic ions. A sealed bomb decomposition was also discussed for the determinations of As, Se and Hg. The lanthanide patterns obtained by Leedy chondrite normalization showed smooth curves.
