Study on Sampling Behavior of Multielements for a Stream Sediment Matrix Material With Nuclear Analytical Techniques

For making an effort to explore procedure for development of CRMs for quality control of solid sampling microanalysis, sampling behavior of multielements for a home-made stream sediment matrix material was studied by using three nuclear analytical techniques (INAA, PIXE and SRXRF) for sample with size covering 9 orders of magnitude (ranging from 10^-1 g to 10^-10 g). It is founded that a series of elements have satisfied sampling behavior on different sampling levels.
