9526956 Neal This grant awards $80,000 as two years partial support of the costs of an equipment upgrade and a graduate student to develop laser ablation, inductively coupled plasma mass spectrometry (LA-ICP-MS) as a routine analytical tool for direct determination of trace element abundance in geological samples at the micro-scale. The work entails an upgrade to their current IR laser ablation torch to include shorter wavelengths including green and ultra-violet light, and will examine the influence of laser wavelength on the need for matrix matching of samples with external standards. ***

9526956 NEAL这笔赠款授予了80,000美元，因为两年的部分支持设备升级的成本和研究生，以开发激光消融，电感耦合等离子体质谱（LA-ICP-MS）作为常规的分析工具，用于直接确定Micro-Scale地质样本中的微量元素。 该作品需要升级其当前的IR激光消融火炬，包括较短的波长，包括绿色和超紫光，并将检查激光波长对与外部标准品的矩阵匹配的需求的影响。 ***
