The application of inductively coupled plasma mass spectrometry (ICP-MS) for determination of boron in water and urine samples was described. The detect limit (3σ) was 0.057 μg/L. The precision of the method was les...
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 ...
Using ultra-fine sample for determination 42 elements by pressurized acid digestion -ICP-MS, the mass of test portion can be reduced to 2 mg yet maintain the representation. And acid used for digestion could be reduce...
Six massive ores in the Jinchuan deposit were dated by Re-Os technique. The Os concentrations and isotopic ratios were determined by N-TIMS, while Re and Pt concentrations were determined by ICP-MS. The samples gave a...
