Acquisition and Replacement of X-Ray Fluorescence Spectro- meter

WHOI化学系现有的x射线荧光光谱仪已经使用了13年，已经达到了高效运行的极限。由于故障造成的停机时间已经增加到非常高的水平。这个系统现在已经过时了，升级或修理的费用太高了。在该合同中，将购买飞利浦PW1404光谱仪，这将提高精度和准确性，提高效率和成本效益，增加可分析元素的数量，并将为其他工作人员提供广泛应用和使用的设备。其他几个NSF支持的项目将立即受益于这次采购。

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.
