儀器名稱:磁選機
LB-1 Magnetic Barrier Laboratory Separator
功能介紹:
Material is fed through the hopper, which provides adjustable, stable flow into a suitable feed trough and then onto the chute.
Material is deflected by opposed magnetic and non-magnetic (gravitational) forces, controlled by the current and side slope respectively. This process is visible in front of the pole pieces.
Continuous deflection as the material moves down the chute separates particles of desired susceptibility.
Material is physically segregated by a divider on the chute near the end of the separating space.
Segregated materials are discharged into separate receiving containers.
儀器名稱:雷射剝蝕感應耦合電漿質譜儀
New Wave UP-213
Agilent 7500cx
功能介紹:雷射剝蝕感應耦合電漿質譜儀(Laser Ablation Inductively Coupled Plasma Mass Sepectrometry,簡稱 LA-ICPMS),其主要裝置為一部雷射和一部感應耦合電漿質譜儀所組成。ICP-MS是使用Agilent ICP-MS 7500cx以Ar和He作為截氣,然後以New Wave UP-213 laser ablation system為配合的進樣系統,標本經由LA聚焦單點剝蝕,利用He做為剝蝕物質的截氣,其碎屑送入ICP-MS後,進行同位素分析,即可得到鋯石的年代。
