This Small Business Innovation Research Phase I project will support the development of a new Differential Mobility Analyzer aerosol sizing and counting system that is simple to use, inexpensive, can be easily deployed for remote, autonomous operation, and allows rapid observations of ambient particle number size distributions over the 0.005 to 0.35 micrometer diameter range. The new technology will largely eliminate the cost, size, weight, and operator-expertise limitations of currently available sizing technologies. A theoretical model of instrument response and mechanical designs of the various components will be completed during the project. A prototype of the sizing system will be fabricated and the instrument will be tested side-by-side against standard instruments in the laboratory. Applications of the new technology include aerosol health effects studies, routine monitoring of ambient aerosol size distributions, studies of rapid aerosol evolution in power-plant plumes, and radiative closure calculations that relate key aerosol properties to ambient light extinction.

这个小型企业创新研究第一阶段项目将支持开发一种新的差分迁移率分析仪气溶胶测量和计数系统，该系统简单易用，价格低廉，可以轻松部署用于远程自主操作，并允许快速观测环境中0.005至0.35微米直径范围内的颗粒物数量尺寸分布。这项新技术将在很大程度上消除目前可用的施胶技术的成本、尺寸、重量和操作员专业知识的限制。在项目期间，将完成仪器响应的理论模型和各部件的机械设计。测量系统的原型将被制造出来，该仪器将在实验室中与标准仪器进行并排测试。新技术的应用包括气溶胶健康影响研究、环境气溶胶尺寸分布的常规监测、发电厂羽流中气溶胶快速演变的研究，以及将关键气溶胶特性与环境光消光联系起来的辐射闭合计算。
