MRI: Acquisition of a Combined GC and HPLC System for Undergraduate Research and Training

0115905 Malloy通过主要研究仪器（MRI）计划资助的这笔赠款为德克萨斯州休斯顿的圣托马斯大学的本科生研究和培训提供了气相色谱（GC）和高效液相色谱（HPLC）相结合的系统。该系统最初将用于化学和环境研究的教师和本科生进行的环境和其他研究项目。该系统包括一个自动化HPLC（配有自动进样器、二极管阵列检测器）和一个气相色谱系统（配有GC自动进样器系统）、计算机和相关软件，这些软件将作为两个系统之间的通用接口运行。 此外，补助金还包括维修用品和服务合同。这项设备赠款支持的初步项目包括空气污染物的痕量检测和测量，特别是与臭氧形成有关的空气污染物，这是休斯顿地区的一个首要问题。相关研究包括分析臭氧化饮用水中类似类型的含氧化合物。第二个项目是分析大二有机实验室的葡萄酒样品中的成分。葡萄酒酿造已被列入有机课程的一部分超过20年，这一增加将允许集成分析的各种组件，包括多功能组件，被集成为实验室的特殊项目。仪器的自动化性质将允许在短时间内有效处理50多个葡萄酒样品。第三个项目涉及调查用于检测和定量饮用水中氨基甲酸酯和相关物种的HPLC方法。 一旦方法开发阶段完成，将分析当地饮用水样品中是否存在这些分析物，并确定污染水平。第四个项目是结合有孔虫实验室的发展使用化学分析。该大学的环境研究计划积极参与有关使用底栖有孔虫和介形虫来确定德克萨斯州海岸海湾环境中水质的研究。 这一设备的购置将补充和补充该部门现有的电子电离和正负化学电离的GC/MS设备的工作。除了研究项目，设备的自动化性质将允许整合到正常的实验室课程工作。最近与生物系的一名成员在项目上的合作导致了未来使用这种设备的可能性。

0115905MalloyThis grant, funded through the Major Research Instrumentation (MRI) Program provides support for the acquisition of a combined gas chromatography (GC) and high performance liquid chromatography (HPLC) system for undergraduate research and training at the University of St. Thomas in Houston, TX. This system will be used initially for environmental and other research projects conducted by faculty and undergraduate students in Chemistry and Environmental Studies. The system comprises an automated HPLC with an autosampler, diode array detector, and a gas chromatography system with a GC autosampler system, computer and associated software, which will operate as a common interface between the two systems. In addition, maintenance supplies and a service contract are included in the grant. The initial projects supported by this equipment grant include trace detection and measurement of air pollutants, particularly those related to ozone formation, an issue of prime importance in the Houston area. Related research includes analysis for similar types of oxygenates in ozonated drinking water. The second project has to do with analysis of components in wine samples from the sophomore organic laboratory. Winemaking has been included as part of the organic curriculum for over 20 years and this addition will allow integration of analysis for various components, including multifunctional components, to be integrated as special projects in the laboratory. The automated nature of the instrumentation will allow efficient processing of the 50+ wine samples in a short time period. The third project involves the investigation of HPLC methods for the detection and quantitation of carbamates and related species in drinking water. Once the method development stage is complete, samples of local drinking water will be analyzed for the presence of these analytes and the contamination level determined. The fourth project is the use of chemical analysis in conjunction with the development of a Foraminiferal Laboratory. The environmental studies program at the University is actively engaged in research concerning the use of both benthic foraminifera and ostracodes in the determination of water quality in the environments of the bays of the Texas coast. This equipment acquisition will complement and supplement work on GC/MS equipment for both electron ionization and positive and negative chemical ionization already present in the department. In addition to research projects, the automated nature of the equipment will allow integration into normal laboratory course work. Recent collaboration on projects with a member of the Biology department has led to future possibilities for use of this equipment.***
