中文摘要 | 在以熱游離質譜儀分析岩石中鍶、釹同位素時,分離岩石中含量極微的鍶、釹及 釤是很不容易的,而色層分析材料RE-Resmn及Sr-Specs提供了一個有效率的途徑。在分析 過空白樣本之釹、鍶含量及 87Sr/86Sr,143Nd/144Nd比值後,顯示溶解岩樣的酸及空氣中 灰塵的污染所產生的背景值很低。 |
英文摘要 | Use of extraction chromatographic procedures involving RE-Resin and Sr- Specs materials offers a rapid method for the separation of microgram quantities of Sr, Nd, and Sm from rocks for analysis by thermal ionisation mass spectrometry. Measurements of blank Nd, Sr concentrations and 86Sr/87Sr, 143Nd/144Nd compositions indicate only minor amounts of background contamination from acids used in the sample dissolution procedure and from airborne dust. |
