摘要
To improve precision of analytical results of pressurized acid digestion-ICP-MS, the first step is to improve the homogeneity by reducing the particle size of sample. Using of ultra-fine sample (-500 mesh) can reduce the mass of the sample and the acid. The satisfactory precision is achieved at 2 mg sampling mass.
