QC/QA and a LIMS in the Undergraduate Analytical Laboratory

现代化学实验室最重要的实用程序包括数据采集和分析、质量控制和质量保证(QC/QA)以及实验室信息管理系统(LIMS)的使用。让化学和化学工程专业的学生接触到所有这些程序是很重要的。目前，匹兹堡大学向本科生教授分析化学的教员在提供QC/QA和LIMS技术方面的教学能力受到限制，因为没有足够的计算机来处理学生的负载，而且现有的实验室计算机没有联网到中央数据库。八台新计算机、一台服务器、打印机和网络硬件/软件组成了分析化学/仪器分析实验室所需的网络系统，供学生使用。新设备可以完成以下项目：1)修改现有实验，引入利用计算机网络进行数据分析和显示的新实验；2)建立教学材料和帮助文件的中央数据库；3)建立LIMS数据库和一套程序；4)开发包含理论和实验的实验室手册，教授QC/QA和LIMS概念；5)制作基于计算机的教学材料。

Among the practical procedures that are most important in modern chemical Among the practical procedures that are most important in modern chemical laboratories are data acquisition and analysis, quality control and quality assurance (QC/QA), and the use of laboratory information management systems (LIMS). It is important that chemistry and chemical engineering students be exposed to all of those procedures. At present, the faculty teaching analytical chemistry to undergraduates at the University of Pittsburgh are restricted in their ability to provide instruction in QC/QA and LIMS techniques because there are not enough computers to handle the student load, and the existing laboratory computers are not networked to a central database. Eight new computers, a server, printer, and network hardware/ software form the required networked system for use by students in the analytical chemistry/instrumental analysis laboratory. The new equipment allows completion of a project to: 1) modify current experiments and introduce new experiments that utilize the computer network for data analysis and display; 2) establish a centralized database of instructional material and help files; 3) set up a LIMS database and set of procedures; 4) develop laboratory manuals that contain both theory and experiment to teach QC/QA and LIMS concepts and 5) produce computer-based instructional material.
