This Small Business Innovation Research (SBIR) Phase II project will address the need for analyzers to detect the toxic species benzene, toluene, ethylbenzene, xylene, (BTEX) and 1,3-butadiene in ambient air. These toxic volatile organic compounds (VOC) are released during incomplete combustion of fossil fuels, the manufacture of a range of chemicals, and the process of petrochemical refining. Entanglement Technologies proposes to complete development of a BTEX and butadiene vapor analyzer based on the combination of cavity ring-down spectroscopy (CRDS) and diffusion time-of-flight (DiTOF). CRDS provides extremely sensitive detection while diffusion provides specificity. The research objective of this project is to demonstrate the full capabilities of this analyzer technology. The project will comprise building a prototype CRDS/DiTOF analyzer to perform laboratory and field trials of the technology. The anticipated benzene sensitivity is 10 parts per trillion by volume in a measurement of less than 10 minutes, surpassing existing technologies. The outcome of the project will be a design for a manufacturable analyzer. The broader impact/commercial potential of this project is to extend the sensitivity of state-of-the-art commercial CRDS analyzers have for small molecules (e.g. carbon dioxide or ammonia) to the detection of more complex molecules. DiTOF provides the ability to distinguish among larger molecules (benzene and other aromatics, aldehydes and ketones) that CRDS alone does not possess. The CRDS/DiTOF analyzer design developed in this project will be Entanglement Technologies? commercial platform design, easily adapted to many different trace gases, including atmospheric and building-interior pollutants, and combinations of trace gases. Such a family of analyzers will impact pollution research, control, and mitigation as much as existing commercial carbon dioxide, methane, and water CRDS analyzers are currently impacting the study of greenhouse gases and climate change. In the long term, CRDS/DiTOF technology will be applied to biomedical science, industrial process monitoring, environmental remediation and explosives detection. For example, the diffusion-based selectivity will prove critical to the separation and quantification of the many hydrocarbon gas components in human breath useful for non-invasive diagnosis of disease. Similarly, CRDS/DiTOF can enable sensitive chemical analysis of liquids such as blood.

这个小型企业创新研究(SBIR)第二阶段项目将满足分析器的需求，以检测环境空气中的有毒物种苯、甲苯、乙苯、二甲苯、苯系物(BTEX)和1，3-丁二烯。这些有毒的挥发性有机化合物(VOC)在化石燃料的不完全燃烧、一系列化学品的制造和石化精炼过程中释放。纠缠技术公司计划完成基于腔衰荡光谱(CRDS)和扩散飞行时间(DiTOF)相结合的BTEX和丁二烯蒸汽分析仪的开发。CRDS提供了极其灵敏的检测，而扩散则提供了特异性。本项目的研究目标是展示该分析仪技术的全部能力。该项目将包括建造一台CRDS/DiTOF分析仪原型，以进行该技术的实验室和现场试验。在不到10分钟的测量时间内，苯的预期灵敏度为万亿分之10，超过了现有技术。该项目的成果将是设计一种可制造的分析仪。该项目的更广泛的影响/商业潜力是将最先进的商用CRDS分析仪对小分子(例如二氧化碳或氨)的灵敏度扩展到对更复杂分子的检测。DiTOF提供了区分较大分子(苯和其他芳烃、醛和酮)的能力，这是CRDS本身所不具备的。在这个项目中开发的CRDS/DiTOF分析仪设计将是纠缠技术？商用平台设计，可轻松适应多种不同的痕量气体，包括大气和建筑内部污染物，以及痕量气体的组合。这样的分析仪系列将影响污染研究、控制和缓解，就像现有的商用二氧化碳、甲烷和水CRDS分析仪目前正在影响温室气体和气候变化的研究一样。从长远来看，CRDS/DiTOF技术将应用于生物医学、工业过程监测、环境修复和爆炸物检测。例如，基于扩散的选择性将被证明对分离和量化人体呼气中的许多碳氢化合物气体成分至关重要，这些气体成分对疾病的非侵入性诊断有用。同样，CRDS/DiTOF可以对血液等液体进行敏感的化学分析。
