This Small Business Innovation Research Phase I project proposes to demonstrate the feasibility of rapidly and quantitatively detecting ten different toxic elements found in consumer products with a portable high definition x-ray fluorescence (HDXRF) analyzer. The objective is to develop a new innovative analyzer with a new small spot x-ray source, tri-chromatic beam, and energy dispersive XRF detection that will provide a definitive pass-fail for products tested on the factory floor. In Phase I, the team will demonstrate the feasibility of measuring these toxic elements in a benchtop setup. The analyzer will have detection limits at sub parts per million levels.The broader impacts of this research are that American manufacturers, distributors, and retailers will be able to preserve their competitive position by becoming compliant in a cost-effective way to the new regulations such as the Consumer Product Safety Improvement Act regulating lead and other toxic elements in consumer products. Currently, there is no measurement technique available outside the laboratory with sufficient accuracy, spatial resolution, and speed to use as a definitive pass-fail method on the factory floor. There is a major public health benefit. The public can be certain the products they buy are safe and free from toxic element contaminations that have been linked to serious health issues such a neurological disorders and kidney damage.

该小型企业创新研究第一阶段项目旨在证明使用便携式高清晰度X射线荧光（HDXRF）分析仪快速定量检测消费品中十种不同有毒元素的可行性。其目标是开发一种新的创新分析仪，该分析仪具有新的小斑点X射线源、三色光束和能量色散XRF检测，将为工厂车间测试的产品提供明确的通过-失败。在第一阶段，该团队将证明在台式装置中测量这些有毒元素的可行性。该分析仪的检测限将达到百万分之几的水平。这项研究的更广泛影响是，美国制造商、分销商和零售商将能够通过以具有成本效益的方式遵守新法规来保持其竞争地位，例如监管消费品中铅和其他有毒元素的《消费品安全改进法案》。目前，在实验室之外，还没有一种测量技术具有足够的精度、空间分辨率和速度，可在工厂车间用作确定的通过-失败方法。这是一个重大的公共卫生效益。公众可以确定他们购买的产品是安全的，没有有毒元素污染，这些污染与严重的健康问题有关，如神经系统疾病和肾脏损伤。
