The processing of high quality chemical products requires accurate measurements and control of chemical composition using on-line devices and computer-assisted data logging and analysis techniques. Moreover, the chemical industry is now expanding its efforts to compete in the new areas of biotechnology, electronics, and advanced materials. Yet, the existing undergraduate laboratory experiments emphasize classical fluid flow, heat transfer, and fluid phase separation applications. They focus on direct measurements of temperature, pressure, and flow using manual recording of data and equipment no longer current in industrial practice. The extensive redesign of undergraduate laboratories to include experiments involving on-line composition measurements using spectroscopic and chromatographic techniques, and micro-computer based data logging systems is undertaken. Each experiment is designed by faculty groups active in research in the technologies involved. Six major experiments are undertaken: two in the biochemical area, two in processing of electronic materials, one in the polymer area and one involving a shape- selective zeolite catlyst. The instruments are also used in eight shorter-term analysis experiments. The two sets of experiments are integrated into our two course chemical engineering laboratory sequence required of all undergraduates and thus will impact 600 engineers laboratory over a five year period. Documentation and experience will be disseminated to all chemical engineering departments in the US.

高品质化工产品的加工需要精确的 化学成分的在线测量和控制 设备和计算机辅助数据记录和分析 技术. 此外，化学工业正在扩大其 努力在生物技术、电子、 先进的材料。 然而，现有的本科生 实验室实验强调经典的流体流动、加热 转移和流体相分离应用。 他们专注于 直接测量温度、压力和流量， 手动记录数据和设备不再使用， 工业实践。 大学生的广泛再设计 实验室，包括涉及在线合成的实验 使用光谱和色谱技术进行测量， 和基于微机的数据记录系统。 每个 实验是由活跃在研究中的教师团体设计的。 涉及的技术。 进行了六项主要实验： 在生化领域，两个在电子处理领域 材料，一个在聚合物区域，一个涉及形状- 选择性沸石催化剂 这些仪器还用于八个 短期分析实验。 两组实验 被整合到我们的两门课程化学工程实验室 所有本科生的要求，因此将影响600 工程师实验室在五年内。 文件和 经验将传播到所有化学工程 在美国的部门。
