The present x-ray fluorescence spectrometer in the Department of Chemistry in WHOI, is 13 years old and has reached its limit of efficient operation. Downtime due to malfunctions has increased to exceedingly high levels. This system is now obsolete and upgrading or repairing would be too costly. In this award, a Philips PW1404 spectrometer will be purchased which would give increased precision and accuracy, better efficiency and cost-effectiveness, increase the number of elements that can be analyzed and would provide a facility with wide application and usage by other workers. Several other NSF supported projects will be immediately benefited of this procurement.

目前世界卫生组织化学系的X射线荧光光谱仪已有13年的历史，已经达到了有效运行的极限。由于故障导致的停机时间增加到了非常高的水平。这个系统现在已经过时了，升级或维修成本太高了。在该合同中，将购买一台飞利浦PW1404型光谱仪，这将带来更高的精密度和准确度，更好的效率和成本效益，增加可分析的元素数量，并将为其他工人提供广泛的应用和使用设施。其他几个由国家科学基金会资助的项目将立即受益于这项采购。
