This Small Business Innovation Research (SBIR) Phase I project concerns the novel application of cavity-enhanced absorption spectroscopy to determine the carbon isotope ratio of carbon dioxide emitting from deep-sea hydrothermal vents. Although, this isotope ratio has recently been identified as an indicator of biological activity, the currently used analytical methods are expensive and inaccurate. The aim of this Phase I proposal is to design a portable cavity-enhanced absorption spectroscopy system to accurately determine isotope ratios of deep-sea samples in situ. Preliminary results suggest that the system can determine isotope ratios to better than 0.1 percent, which is sufficient to determine the presence of biological activity.This effort will provide an accurate determination of carbon isotope ratios in an inexpensive, portable device. It will also have significant commercial impact in medical diagnostics, the petroleum industry, and environmental monitoring. Projected sales of the ratiometer in the former two areas alone are expected to exceed $65M over the next five years. Moreover, the proposed prototype can be readily modified to monitor various industrial gases, further increasing its commercial impact.

这一小企业创新研究第一阶段项目涉及腔增强吸收光谱法的新应用，以确定深海热液喷口排放的二氧化碳的碳同位素比率。虽然，这种同位素比最近已被确定为生物活性的指标，目前使用的分析方法是昂贵的和不准确的。这一第一阶段提案的目的是设计一个便携式腔增强吸收光谱系统，以便在现场准确确定深海样品的同位素比率。初步结果表明，该系统可以确定同位素比优于0.1%，这是足以确定生物活性的存在。这一努力将提供一个廉价的，便携式设备中的碳同位素比的准确测定。 它还将在医疗诊断、石油工业和环境监测方面产生重大的商业影响。预计未来五年内，仅在前两个地区，比率计的销售额就将超过6500万美元。此外，拟议的原型可以很容易地修改，以监测各种工业气体，进一步增加其商业影响。
