The utilization of a laboratory-constructed programmable, cryogenic gas chromatograph (KEDBOR1OIR1) for use in air pollution studies is presented. The instrument (J. Chromatogr., 89(1974) 1) is modular in design and incorporates many commercially available components as well as a few "scratch-built" parts. A temperature control range of --100 degrees C to plus 300 degrees C, with five programmable rates, is possible using this particular instrument. The instrument is capable of dual-column and dual-detector operation. Data have been gathered from laboratory-prepared samples as well as from samples obtained from an air pollution study in the Philadelphia area. Small amounts (ppm or less) of the gaseous hydrocarbons and the common inorganic gases (NOx,SOx,CO, CO2, H2S, COS) are detected and quantitated. Calibration curves for each gaseous component have been constructed and the analyzed samples compared to them for quantitative data. Data and information from the use of several different columns, sampling sites and their locations are presented. Experimental data agreed favorably with the current findings and discussions of air pollution problems.
介绍了一种实验室构建的用于空气污染研究的可编程低温气相色谱仪（KEDBOR1OIR1）的应用。该仪器（《色谱杂志》，89(1974) 1）采用模块化设计，包含许多商用组件以及一些“自制”部件。使用这台特定仪器，温度控制范围为-100摄氏度至+300摄氏度，有五种可编程速率。该仪器能够进行双柱和双检测器操作。数据已从实验室制备的样品以及从费城地区空气污染研究中获得的样品中收集。检测并定量了少量（ppm或更低）气态烃类和常见无机气体（氮氧化物、硫氧化物、一氧化碳、二氧化碳、硫化氢、羰基硫）。构建了每种气态成分的校准曲线，并将分析样品与之比较以获取定量数据。给出了使用几种不同色谱柱、采样点及其位置的数据和信息。实验数据与当前关于空气污染问题的研究结果和讨论结果吻合良好。
