人类嗅觉和电子鼻在气味测量中的运用对比

Application and Comparison of Olfactometry and Electronic Noses in Odour Detection

分析了动态嗅觉测量法、气相色谱质谱—嗅觉测量法以及电子鼻测量法的技术优缺点。以垃圾填埋场与堆肥设施的气味检测为例,对嗅觉测量法与电子鼻测量法进行了技术对比。动态嗅觉测量法提供了某一地点气味的浓度数据,但无法持续实地测量,耗时严重并且成本高昂;电子鼻测量法分析成本较低并可以快速获得检测结果,可以实施持续性实地监测。经过训练的电子鼻加上合适的数据处理方法,能够有效地解决气味持续监测的问题。

The article aims to present the advantages and disadvantages of odour detection technologies of olfactormery,Gas Chromatography Mass Spectrometry coupled with olfactometric detection（ GC-MS/O）,electronic-noses. The applications of olfactometry and electronic-noses were compared in landfill and composting facility.Dynamicolfactometry provided point odour concentration data did not allow continuous and field measurements. It was too time-consuming and quite expensive. Electronic noses presented lower analysis costs and quick results and allowed continuous monitoring. Some studies demonstrated that a trained electronic nose and suitable data processing methods could represent a valid solution to the problem of continuously monitoring odour.
