This proposal is for purchase of a 213 nm Nd YAG*laser sampling system for trace element microanalysis of solids in the UVic ICP-MS*laboratory. The desired instrument is a New Wave Research NWR213 system*supplied by Ligero Techical Services. The instrument is to be funded through a combination of NSERC*funds we seek herein, with $40K of our own contributions from lab user fee*savings, and departmental and external support funds. The new device is to replace an aging 12 year old instrument, that has undergone many repairs and is becoming difficult to source parts for. The new NWR213 system has many modern*features we require to develop high resolution, 2-dimensional trace element*mapping in solids (minerals, hair, shells, otoliths, artefacts) that will inform*spatial and temporal changes in the environmental conditions under which they*form. The NWR213 device has beam-shaping capability that allows for square-shaped*laser ablations, in either straight or sinuous paths, allowing compositional imaging of trace elements in minerals or biological*materials orthogonal to growth bands with no beam overlap. In addition, the 2-volume*sample cell chamber of the NWR213 system has a smaller gas sampling volume, giving a 20-fold faster gas washout time and thus much higher sensitivity. A customizable*sample holder area for flexible sample options. These features make 2-D trace*element mapping practical, accurate, and precise. Higher sensitivity is also necessaryto advance*our capabilities and potential in geochronology and geochemistry. Purchasing 13 nm Nd YAG laser sampling system is timely, allowing for higher valued trade-in of our older instrument, and prudent,*by avoiding investment of our user fee funds toward frequent and time-consuming*repairs of our aging instrumentation. The investment of our own*contributions that total to ~30% of the purchase, shows our commitment to more modern*state-of-the-art analytical technology that will further advance the training of the next*generation researchers in geology, environmental science, geochronology, oceanography*and biology.

该提案是用于购买213 nm nd yag*激光抽样系统，用于在UVIC ICP-MS*实验室中的固体微分析。所需的仪器是Ligero Techical Services提供的新浪潮研究NWR213系统*。该工具将通过我们在此寻求的NSERC*资金的组合提供资金，并从实验室用户费用*节省以及部门和外部支持资金中提供4万美元的捐款。新设备是要替换一种已经经历了许多维修的年龄的12岁仪器，并且很难为零件提供零件。新的NWR213系统具有许多现代*，我们需要开发高分辨率，二维微量元素*固体（矿物，头发，壳，耳石，耳石，人工制品）中的映射，这些功能将告知*环境条件中的空间和时间变化他们*形式。 NWR213设备具有光束成型功能，可以在直线或弯曲的路径中进行方形的*激光消融，从而可以在矿物质或生物学*材料与没有光束重叠的生长带正交的痕量元素或生物学*材料中的痕量成像进行组成成像。此外，NWR213系统的2卷*样品池室具有较小的气体采样量，给出了20倍快20倍的气体清洗时间，从而更高的灵敏度。 可自定义的*样品持有人区域，用于灵活的样品选项。这些功能使2-D跟踪*元素映射实用，准确和精确。还必须提高灵敏度才能提高我们的能力和地质学和地球化学的潜力。购买13 nm nd yag激光抽样系统是及时的，可以通过避免投资我们的用户费用资金来频繁且耗时*维修我们的老化仪器，从而允许我们较旧的仪器进行更高的价值交易。我们自己的*捐款的投资总计约为购买的30％，这表明了我们对更现代的*最先进的分析技术的承诺，该技术将进一步促进下一个*一代*地质研究人员，环境科学的培训，地质学，海洋学*和生物学。
