STTR Phase I: Planar Array Infrared (PA-IR): A Compact Rugged Double Beam Infrared Spectrometer for Laboratory and Field Analysis

这项小型企业技术转让（STTR）第一阶段研究项目将展示红外平面阵列技术在研究水污染物（如工业污染物和生物杂质）方面的实用性。提出设计和构建一种紧凑、高灵敏度、基于焦平面阵列检测的双光束红外仪器，该仪器达到或超过市售设备的性能标准，并能够在环境中运行，以提供稀浓度有机和生物污染物的测量。红外光谱具有分子特异性，可提供污染物的定性鉴定和浓度的定量测量。然而，现有的基于傅里叶变换技术的红外仪器在环境条件下快速进行这些测量的能力有限。这项研究将应用这项创新技术，实现生产现场（如化学公司现场）的实时污水检测，通过主动识别和测量污染物的存在，实现切实的节约。这种可重构的便携式仪器将帮助在分析实验室工作并需要高速测量和/或参与环境监测的科学家（学术，工业和政府），其中传感速度很重要。

This Small Business Technology Transfer (STTR) Phase I research project will demonstrate the utility of infrared planar array technology to study water pollutants such as industrial contaminants and biological impurities. It is proposed to design and build a compact, high-sensitivity, double beam infrared instrument based on focal plane array detection, which meets or exceeds performance standards of commercially available devices and is able to operate in ambient environments to provide measurements of dilute concentrations of organic and biological contaminants. Infrared spectroscopy has the molecular specificity to provide both qualitative identification of contaminants and quantitative measurement of concentrations. However, existing IR instruments based on Fourier transform techniques are limited in their ability to make these measurements rapidly under ambient conditions. The research will apply this innovative technology to enable real time effluent detection from a manufacturing site such as that found at chemical company sites to realize tangible savings from being able to pro-actively identify and measure the presence of pollutants. This reconfigurable and potentially portable instrument will assist scientists (academic, industrial and government) who work in analytical labs and require high speed measurements and/or those involved in environmental monitoring where sensing speed is important.
