| The Improvement of Age Determination Technique for Pitchblende |
| In this study, ID-HR-ICP-MS was used to detect the content of uranium in pitchblende, and a new separation method was employed to separate uranium from lead. With the measures adopted, the speed of determination was improved, and the amount of sample and the blank of procedure were greatly reduced. |
