SBIR Phase I: Multi-Species Atmospheric Field Analyzer

该小型企业创新研究第一阶段项目将确定适用于检测多种痕量大气物种的新型激光光谱仪的性能和操作规范。坚固、紧凑的传感器头将略大于一罐苏打水，并在几秒钟内为多个物种提供低于十亿分之一（ppb）的灵敏度。第一阶段将证明对甲醛、CO和乙炔的灵敏度。批量生产的价格将与目前仅检测单一物种的痕量气体传感器竞争。完全开发的坚固原型将适用于地面和空中大气测量应用中的痕量物种探测。光谱仪的选择性和多物种灵敏度在一个有竞争力的价格点将使气候研究人员部署在应用中，以前需要多个传感器的单一传感器。该项目将产生比竞争技术更小，更便宜，更坚固的传感器。有毒痕量大气物种污染环境，温室气体影响全球气候变化。该项目将通过提供阐明全球气候变化趋势的测量数据，对社会产生更广泛的影响。其他影响将在职业安全和确保法规遵守方面发现。基本技术应扩展到其他痕量气体检测应用，包括生物医学呼吸诊断。

This Small Business Innovation Research Phase I project will determine the performance and operating specifications for a new laser spectrometer suitable for detection of multiple trace atmospheric species. The rugged, compact sensor head will be slightly larger than a can of soda and provide below parts-per-billion (ppb) sensitivity in a few seconds, for multiple species. Sensitivity for formaldehyde, CO and acetylene will be demonstrated in Phase I. The price point with volume production will be competitive with present trace gas sensors that only detect a single species. The fully developed rugged prototypes will be suitable for detection of trace species in both ground-based and airborne atmospheric measurement applications. The selectivity and multiple species sensitivity of the spectrometer at a competitive price point will enable climate researchers to deploy a single sensor in applications where multiple sensors would previously be required. This project will result in sensors that are smaller, less expensive, and more rugged than competing technologies.Toxic trace atmospheric species contaminate the environment and greenhouse gases affect global climate change. This project will have broader impacts on society by providing measurements that illuminate the trends in global climate change. Other impacts will be found in occupational safety and insuring regulatory compliance. The basic technology shall extend to other trace gas detection applications including biomedical breath diagnosis.
