| Abstract: | Odor sensitive unit of the smell-seeing electronic nose for trimethylamine detection is developed.Rules of choosing color sensors and methods of designing lamphouse are presented.Trimethylamines gases of eight different concentrations are tested by the home-made smell-seeing electronic nose.A principle component analysis(PCA)shows that among the eight samples,seven concentrations related to human health are linearly discriminable.The system’s limit of detection(LOD)is under 50 particles per billion(×10-9),and the sensitive units are repeatedly usable under concentration of 8 particles per million(×10-6). |
