Dymerski T., Gebicki J., Namiesnik J., 2014, Comparison of Quality Evaluation of Agricultural Distillates Using Prototype of Electronic Nose and Fast/Flash GC, Chemical Engineering Transactions, 40, 127-132.
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.
