This paper presents an efficient electronic nose (e-nose) system, named “NOS.E”, for odour analysis and assessment. In addition to the reliable hardware and software designs, an airflow intake system is implemented to ensure the precise odour analysis procedure in the NOS.E system. Additionally, a particular control logic was introduced to improve the test efficiency of the NOS.E by reducing operation time. Furthermore, the fault detection and alarming design can generate a high-reliability performance by constantly monitoring its working status. To evaluate the performance of the NOS.E, three types of alcohols were tested by the NOS.E and compared to data collected by comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC×GC-TOFMS). The results indicate that the NOS.E can successfully distinguish three different alcohols with high efficiency and low cost and has the potential to be a universal odour analysis platform implemented in various applications.

用于气味分析和评估的高效电子鼻系统设计

本文提出了一种有效的电子鼻(e-nose)系统,名为“ NOS.E”,用于气味分析和评估。除了可靠的硬件和软件设计之外,还采用了气流进气系统,以确保NOS.E系统中的精确气味分析程序。另外,引入了一种特殊的控制逻辑,以通过减少操作时间来提高NOS.E的测试效率。此外,故障检测和报警设计可以通过不断监视其工作状态来产生高可靠性。为了评估NOS.E的性能,通过NOS.E测试了三种类型的醇,并将其与通过综合二维气相色谱和飞行时间质谱(GC)收集的数据进行了比较。×GC-TOFMS)。结果表明,NOS.E可以高效,低成本地成功区分三种不同的醇,并有可能成为在各种应用中实施的通用气味分析平台。
