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

这个小型企业创新研究(SBIR)第一阶段项目提出了改进气溶胶颗粒中个别有机化合物测量的迫切需要。由于气雾剂对全球气候和人类健康的影响，以及对药物输送等工业应用的影响，气雾剂至关重要。该项目旨在开发一种新的气溶胶收集器模块(ACM)，它将允许以无伪影的方式积累足够的气溶胶质量，以便以高时间分辨率(30分钟)近实时地分析气溶胶成分。通过各种分析仪器。ACM将使用Aerodyne公司在其非常成功的气溶胶质谱仪(AMS)中实施的技术来将气溶胶与气相分离。ACM将包括：1)新的低温收集器；2)接口模块，用于对收集到的气溶胶进行热解吸；3)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，并可能扩大到包括监管监测努力和过程工业实验室。ACM将首次实现对气溶胶中存在的单个有机物种的近乎实时的分析，并将以比现有分析方法低得多的成本销售。要了解和减轻颗粒物对气候的影响和对健康的影响，以及确定和改进工业气溶胶技术，就需要有能力测量气溶胶尺寸分辨的有机成分。

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.
