Abstract
The amount of 10~(-8)g of uranium was measured by mass spectrometry isotopedilution with a Varian MAT--260 mass spectrometer. The suitable working condit-ions and the suitable isotope ratio of mixed samples were selected. The solutionwas entirely loaded on a evaporation filament by using a pipette. The accuracy ofthe measurement was better than ±2%.
