The paper presents the results of investigation on quality evaluation of agricultural distillates using a prototype of electronic nose instrument and a commercial electronic nose of Fast/Flash GC type -HERACLES Ⅱ. The prototype was equipped with a set of six semiconductor sensors by FIGARO Co.. In case of the prototype volatile fraction of the agricultural distillate was prepared via barbotage process. HERACLES Ⅱ analysed the headspace fraction. Classification of the samples into particular quality classes was performed using linear discriminant function supported with cross-validation method. Almost 100 % correct classification of agricultural distillate was observed for the analyses with HERACLES Ⅱ. The prototype of electronic nose provided correct classification of 70 % of the samples.
