SBIR Phase I: Innovative Aerosol Collector for On-Line Analysis of Organics

这个小企业创新研究（SBIR）第一阶段项目旨在解决改进气溶胶颗粒中单个有机化合物测量的关键需求。由于气溶胶对全球气候和人类健康的影响，以及对制药药物输送等工业应用的影响，它们至关重要。该项目旨在开发一种新的气溶胶收集器模块（ACM），该模块将允许以无伪像的方式积累足够的气溶胶质量，以便通过各种分析仪器以近实时的高时间分辨率（30分钟）分析气溶胶成分。ACM将使用Aerodyne在其非常成功的气溶胶质谱仪（AMS）中实施的技术将气溶胶从气相中分离出来。ACM将包括：1)一个新的低温收集器2)一个热解吸收集的气溶胶的接口模块3)一个流量控制。ACM的商业市场将包括政府、学术和工业研究实验室，并可能扩展到包括监管监测工作和过程工业实验室。ACM将首次允许对气溶胶上存在的单个有机物种进行近实时分析，并将以比现有分析方法低得多的成本上市。为了理解和减轻颗粒物对气候的影响和对健康的影响，以及为了表征和改进工业气溶胶技术，测量气溶胶大小分解有机成分的能力是必要的。

This Small Business Innovation Research (SBIR) Phase I project proposes to adressss the critical need for improved measurements of individual organic compounds in aerosol particles. Aerosols are crucially important due to their effects in global climate and human health, as well to industrial applications such as pharmaceutical drug delivery. This project seeks to develop a new Aerosol Collector Module (ACM) that will allow the accumulation of sufficient aerosol mass in an artifact-free manner for analysis of aerosol composition in near real-time with high- time resolution ( 30 min.) by a variety of analytical instruments. The ACM will use the techniques implemented by Aerodyne in its highly successful Aerosol Mass Spectrometer (AMS) to separate the aerosols from the gas phase. The ACM will consist of: 1) A new cryocollector 2) An interface module to thermally desorb the collected aerosol 3) A flow control. The commercial market for the ACM will include government, academic, and industrial research laboratories and may expand to include regulatory monitoring efforts and process industrial laboratories. The ACM will allow for the first time near real- time analysis of individual organic species present on aerosols and will be marketed at a significantly lower cost than existing analytical methods. The ability to measure aerosol size-resolved organic composition is needed for understanding and mitigating the climate impacts and health effects of particulate matter, and for the characterization and improvement of industrial aerosol technologies.
