This Small Business Innovation Research (SBIR) Phase II project will develop a prototype instrument for measuring harmful bi-products of chlorination in drinking water. These disinfection bi-products are subject to EPA regulations. The Phase I project demonstrated that the concept of differential UV absorption measurement, i.e. absorption before and after chlorination, is suitable for the needed measurement. A pre-production prototype instrument will be constructed during the Phase II project. This device shall employ a multi-pass cell design using our novel dual-ratio technique that eliminates concerns about long term drifts. The overall instrument architecture design and systems design will be carried out prior to assembly of the full microprocessor-controlled recording device. Extensive laboratory and field tests will be used to review design changes before production.The potential commercial applications of the instrument proposed may be used in thelaboratory or in-line at utilities. The market for the proposed product is quite substantial as EPA regulations will result in the installation of such devices at all utilities and drinking water facilities.

这个小企业创新研究（SBIR）第二阶段项目将开发一个原型仪器，用于测量饮用水中氯化的有害副产品。这些消毒副产品符合EPA法规。第一阶段项目表明，差分紫外吸收测量的概念，即氯化前后的吸收，适用于所需的测量。在第二阶段项目期间将建造一个预生产原型仪器。该器件应采用多通池设计，采用我们的新型双比技术，消除了长期漂移的担忧。整个仪器结构设计和系统设计将在组装完全由微处理机控制的记录装置之前进行。在生产之前，将进行广泛的实验室和现场测试，以审查设计变更。拟议的仪器的潜在商业应用可能会用于实验室或公用事业的在线。由于EPA法规将导致在所有公用事业和饮用水设施中安装此类设备，因此拟议产品的市场相当可观。
