Odor Concentration Decay and Stability in Gas Sampling Bags

Journal of the Air & Waste Management Association, 2003
This paper presents results of an experimental study into factors contributing to decay of odor samples during storage, between 4 and 40 hr after sample collection. The odor studied was sampled from a tobacco processing plant as part of collaborative research with a view to establishing a manual outlining methods for odor annoyance management ...

[Study on the relationship between odor intensity and components concentrations of odor mixture].

Huan jing ke xue= Huanjing kexue, 2015
Odor pollution has become a serious environmental problem arising from volatile organic compounds (VOCs) and other pollutants. But the studies on odor intensity and other olfactory evaluations are seriously influenced by the diversity, distinct concentration fluctuation and complex interaction of pollutants. In order to explore the relationship between

Concentrations of Odorous Vapors in Test Chambers

1968
Odor test chambers are used either for evaluation of odor-reducing devices, or to provide odor-free environments in which a jury can measure the odors of materials, products, or foods. It is important to consider the factors that determine the changing and equilibrium concentrations of odorous vapors in such chambers.

Intelligent Electronic Nose System Independent on Odor Concentration

2011
Conventional odor classification methods have been considered under steady state conditions of temperature, humidity, density, etc. In real applications, those conditions may not occur and they will be variable from time to time. Therefore, it is necessary to find some features which are independent on various environmental conditions.
