Cross-Check of PIXE Analysis Between Three Laboratories
PIXE分析技术的国际横向比对结果

In order to confirm the measurement accuracy of PIXE (Particle Induced X-ray Emission), cross-check test were carried out between three laboratories Thirty single element samples and one plural elements sample were used in the test The agreements between three laboratories were evaluated to be better than 10% for the most of tested samples The reproducibility test showed very good agreement and the dispersion in three times repeated PIXE measurements was within 6% on the average
