通过萨凡纳河技术中心(SRTC)和橡树岭国家实验室(ORNL)的合作，一种新的现场收集、浓缩和分离空气中颗粒物的设备正在开发中。这项工作需要将气溶胶-液体颗粒提取系统(ALPES)耦合到电化学调制分离(EMS)单元。ALPES收集空气中的颗粒物并将其浓缩成液体，1 EMS细胞根据它们对带电目标表面的亲和力来分离物种。2初步数据表明，通过连接这些设备可以实现实质性的灵敏度增强。该系统将允许对放射性核素进行快速现场分析，同时与标准辐射测量技术相比，可以减少劳动力、成本和周转时间。
A novel device for collecting, concentrating and separating airborne particles in situ is under development through a collaborative effort between Savannah River Technology Center (SRTC) and Oak Ridge National Laboratory (ORNL). This work entails coupling an Aerosol-to-Liquid Particle Extraction System (ALPES) to an electrochemically modulated separation (EMS) cell. The ALPES collects and concentrates airborne particles into a liquid,1and the EMS cell separates species based on their affinity for a charged target surface.2Preliminary data indicates substantial sensitivity enhancement may be realized by interfacing these devices. The system will allow for rapid field analysis of radionuclides while providing reductions in labor, cost, and turnaround time compared to standard radiometric techniques.
