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

0115905马洛伊这笔赠款由主要研究仪器(MRI)计划提供资金，用于为德克萨斯州休斯敦的圣托马斯大学的本科生研究和培训购买气相色谱(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专业的教师和本科生进行的环境和其他研究项目。该系统包括一个带有自动进样器的自动高效液相色谱系统、二极管阵列检测器，以及一个带有GC自动进样器系统的气相色谱系统、计算机和相关软件，这些系统将作为两个系统之间的通用接口。此外，赠款中还包括维修用品和服务合同。这笔设备赠款支持的最初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那些，这是休斯顿地区最重要的问题。相关研究包括分析臭氧饮用水中类似类型的含氧物。第二个项目是对来自二年级有机实验室的葡萄酒样品进行成分分析。20多年来，葡萄酒酿造一直是有机课程的一部分，这一增加将允许整合各种成分的分析，包括多功能成分，作为实验室中的特殊项目。仪器的自动化特性将允许在短时间内高效地处理50多个葡萄酒样品。第三个项目涉及调查饮用水中氨基甲酸酯和相关物种的高效液相色谱检测和定量方法。一旦方法开发阶段完成，将对当地饮用水样本进行分析，以确定这些分析物的存在和污染水平。第四个项目是在开发有孔虫实验室的同时使用化学分析。该大学的环境研究方案积极参与关于使用底栖有孔虫和介形虫来确定得克萨斯州海岸海湾环境的水质的研究。这项设备采购将补充和补充该部门现有的电子电离和正负化学电离GC/MS设备的工作。除了研究项目，设备的自动化特性将使其能够整合到正常的实验室课程工作中。最近与生物系的一名成员在项目上的合作带来了这种设备未来使用的可能性。*

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.***
