SBIR Phase II: Development of a Cone Penetrometer Membrane Inlet

施密特 这个小型企业创新研究第二阶段项目将证明两个锥形流量计化学检测系统的可行性。这些系统有可能减少补救现场表征的成本，目前估计在美国超过4000亿美元，减少25%。这一成本节约将通过使用配备化学传感器的锥形流量计来实现，而不是目前用于表征补救场地的昂贵的土壤钻探和井监测过程。 第一阶段的工作证明了膜入口组件用于锥形流量计的可行性。第二阶段的工作将证明膜入口组件与两种类型的化学传感器相结合的可行性，能够检测挥发性有机烃（VOC）。 原型探测系统将在实验室中制造和校准，然后在实际污染场地使用标准锥形流量计装置进行测试。 锥形流量计传感器的性能将与EPA批准的分析技术的结果相关联。 预计这项研究将产生两种产品。 第一种是能够真实的实时测量土壤中氯代烃和非氯代烃浓度的系统。 第二个是一个适配器，它允许一个小型气相色谱仪安装在一个锥形流量计。 ***

*** 9629305 Schmidt This Small Business Innovation Research Phase II project will demonstrate the feasibility of two cone penetrometers chemical detection systems. These systems have the potential to reduce the cost of remediation site characterization, which is currently estimated at over $400 billion in the United States, by 25%. This cost savings will be achieved by using chemical sensor-equipped cone penetrometers in place of the expensive soil boring and well monitoring processes currently used to characterize remediation sites. The Phase I effort demonstrated the feasibility of a membrane inlet assembly for cone penetrometers. The Phase II effort will demonstrate the feasibility of combining the membrane inlet assembly with two types of chemical sensors capable of detecting volatile organic hydrocarbons (VOCs). Prototype detection systems will be fabricated, calibrated in the laboratory, and then tested using standard cone penetrometer rigs at actual contaminated sites. The performance of the cone penetrometer sensors will be correlated with the results of EPA-approved analytical techniques. Two products are expected to result from this research. The first is a system which can measure the concentration of both chlorinated and non-chlorinated hydrocarbons in soil in real time. The second is an adapter which permits one to mount a miniature gas chromatograph in a cone penetrometer. ***
