This Small Business Technology Transfer (STTR) Phase I Project concerns the development of field-based analytical instrumentation for the determination of carbon content in soil. The instrumentation will employ laser-induced breakdown spectroscopy utilizing detection of atomic carbon ultraviolet emission. The work plan will focus on a proof-of-principle demonstration using standard soil samples as reference materials. Samples of unknown composition will then be analyzed using the proposed technology. Estimates of precision and accuracy will be determined and compared with values obtained using conventional combustion-based analytical techniques. An economical field-ready instrument will also be designed.Significant amounts of carbon are deposited in the soil by biological activity and, as such, might offer a means of mitigating the effects of anthropomorphically produced carbon dioxide. The resulting need to acquire more accurate terrestrial carbon inventories and measure fluxes will require orders of magnitude more measurements than can be delivered economically using current technology. This project will attempt to develop an economical means of providing such measurements.

小企业技术转让（STTR）第一阶段项目涉及开发用于测定土壤中碳含量的实地分析仪器。该仪器将采用激光诱导击穿光谱法，利用碳原子紫外线发射的检测。工作计划将侧重于使用标准土壤样本作为参考材料进行原理验证示范。然后将使用所提出的技术分析未知成分的样品。将确定精确度和准确度的估计数，并与使用传统燃烧分析技术获得的值进行比较。还将设计一种经济实用的实地仪器，大量的碳因生物活动而沉积在土壤中，因此可能提供一种减轻拟人产生的二氧化碳影响的手段。因此，需要获得更准确的陆地碳清单和测量通量，这将需要比使用现有技术经济地提供的测量多几个数量级。本项目将试图开发一种提供这种测量的经济手段。
