*** 9800923 Carter This Small Business Innovation Research (SBIR) Phase II project will develop a miniaturized Total Organic Carbon (TOC) analysis system for on-site monitoring applications. The analytical technique employs a microfluidic sensor for reliable and rapid measurement of TOC trace quantities in aqueous effluent. Detection relies on photocatalytic mineralization of dissolved and suspended organics to carbon dioxide. Rapid equilibrium of carbon dioxide with carbonate species permits quantification of TOC using a conductivity measurement. Phase I experiments showed advantages over commercially available analytical instruments. Response time of the miniaturized TOC analysis system was four times faster than commercial instruments; only 30 seconds per measurement was required versus 120 seconds for conventional instruments. Phase II enhancements are expected to provide TOC measurements in 2 seconds. Performance enhancements of this magnitude would be a quantum improvement in real-time TOC instrumentation. Rapid, reliable, and reproducible measurements of organic contaminants in aqueous effluent are expected to find commercial applications in the semiconductor, pharmaceutical, drinking water, power generation, and waste water industries. ***

*** 9800923 Carter 这个小型企业创新研究 (SBIR) 第二阶段项目将开发用于现场监测应用的小型化总有机碳 (TOC) 分析系统。 该分析技术采用微流体传感器可靠、快速地测量废水中的痕量 TOC。 检测依赖于溶解和悬浮有机物光催化矿化成二氧化碳。 二氧化碳与碳酸盐物质的快速平衡允许使用电导率测量来定量 TOC。 第一阶段实验显示出优于市售分析仪器的优势。 小型化TOC分析系统的响应时间比商用仪器快四倍；每次测量仅需 30 秒，而传统仪器则需要 120 秒。 第二阶段的增强预计将在 2 秒内提供 TOC 测量。 这种程度的性能提升将是实时 TOC 仪器的巨大改进。 对废水中有机污染物的快速、可靠和可重复的测量预计将在半导体、制药、饮用水、发电和废水行业中找到商业应用。 ***
