Acquisition of a Laser Ablation System for Inductively Coupled Plasma Mass Spectrometers (ICP-MS)

0093645雅各布森这笔赠款支持购买五倍频(193 nm波长)深紫外光(DUV)激光器，以便与哈佛大学地球和行星科学系(EAPS)的电感耦合等离子质谱仪(四极和多收集器)对接。激光消融系统将使需要对地质和地外物质进行现场和空间分辨同位素分析的研究得以继续进行。激光系统将支持哈佛大学几位教员的研究，包括斯坦·雅各布森(壳幔地球化学和宇宙化学)、丹·施拉格(海洋化学和古海洋学)、保罗·霍夫曼(新元古代构造学和气候)和海因里希·霍兰德(地球早期大气的演化)，以及他们的研究生和博士后。***

0093645JacobsenThis grant supports the acquisition of a frequency quintupled (193 nm wavelength) deep ultraviolet (DUV) laser to be interfaced with inductively coupled plasma mass spectrometers (both a quadrupole and a multicollector) in the Department of Earth and Planetary Sciences (EAPS) at Harvard University. The laser ablation system will allow continued studies requiring in situ and spatially resolved isotopic analysis of geological and extraterrestrial materials. The laser system will support research by several faculty members at Harvard including Stein Jacobsen (crust-mantle geochemistry and cosmochemistry), Dan Schrag (marine chemistry and paleoceanography), Paul Hoffman (Neoproterozoic tectonics and climate) and Heinrich Holland (evolution of Earth's early atmosphere) as well as their graduate students and postdocs. ***
