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

摘要

Simultaneous multielement analysis of geochemical andenvironmental samples such as rock, sediment, seawater, and lake waterhave been carried out by inductively coupled plasma atomic emissionspectroscopy (ICP-AES) and inductively coupled plasma mass spectrometry(ICP-MS). In these experiments, some instrumental improvement and samplepretreatment techniques were required to fulfil accurate multielementdetermination of 30-50 elements for each sample described above.Consequently, it becomes possible to characterize the samples bycomparing the profiles of their multielement concentrationdistributions. Such multielement profiling analysis of various samplesmay be useful in the research fields such as geochemistry, environmentalchemistry, material science and so forth
