通过使用大容量有机蒸汽收集设备和适当的样品转移分析技术，结合气相色谱仪排出口处气相色谱仪解析组分的心理物理（感官）气味评估，可以收集大量关于空气样品气味组分清单的信息。这些程序被应用于芝加哥几所大都会学校的空气研究。还对外部空气进行了检查，以评估外部空气污染对有机蒸汽和气味剂造成的学校空气污染的贡献。 然后，使用非参数统计对气相色谱参数进行检查，以确定与空气质量的相关性，该相关性首先使用工程数据和现场观察进行独立排序。引文:宾夕法尼亚州费城ASHRAE Transactions第77卷第1部分

By use of high-capacity organic vapor collection devices and appropriate sample transfer analysis techniques, combined with psychophysical (sensory) odor evaluations of the gas chromatographically resolved components at the effluent port of a gas chromatograph, it is possible to gather considerable insight into the inventory of the odorous components of an air sample. These procedures were applied to a study of air in several Chicago metropolitan area schools. The outside air was also examined, to permit assessments of the contribution of outside air pollution to the air pollution of the school air by organic vapors and odorants. The gas chromatographic parameters were then inspected, using non-parametric statistics for correlations to the air quality which was first independently ranked using engineering data and on-the-spot observations.
