Multielement profiling analysis of geochemical and environmental samples by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and inductively coupled plasma-mass spectrometry (ICP-MS)

摘要

Simultaneous multielement analysis of geochemical and environmental samples such as rock, sediment, seawater, and lake water have been carried out by inductively coupled plasma atomic emission spectroscopy (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS). In these experiments, some instrumental improvement and sample pretreatment techniques were required to fulfil accurate multielement determination of 30-50 elements for each sample described above. Consequently, it becomes possible to characterize the samples by comparing the profiles of their multielement concentration distributions. Such multielement profiling analysis of various samples may be useful in the research fields such as geochemistry, environmental chemistry, material science and so forth.
