Abstract
The paper presents and compares the results of investigation on classification of atmospheric air samples collected in a vicinity of municipal landfill with respect to their odour nuisance. The research was conducted using a prototype of electronic nose instrument and a commercial electronic nose of Fast/Flash GC type – HERACLES II. The prototype was equipped with six semiconductor sensors of TGS type. Classification of the air samples with respect to the place of collection relative to the landfill was performed using quadratic discriminant function (QDA) supported with cross-validation method. More than 80% of the samples were correctly classified employing the analysis with HERACLES II. The prototype of electronic nose provided correct classification of 50% of the samples.
