A reliable procedure for PIXE analysis of thick target sample has been developed, calibrated and standarlized. As part of the QA/QC protocol of the laboratory, several standard samples measured using our thick target PIXE (TTPIXE) analysis procedure. The result indicates good accuracy in determination of trace element concentration over a wide range of elements. The relative differences between measured and certified values are mostly bellow 20 %.
In 2013, about 500 of sediment samples collected near the coastline have been analyzed by PIXE system in the laboratory. Geological samples were extensively analyzed since then.
Analysis of aerosol samples collected at several sites in Vietnam is being proposed.
